Amsonia
'Blue Ice'
Blue Star
|
Our favorite new variety of Amsonia! This new selection of Amsonia from
White Flower Farm bears gorgeous plump navy blue buds in late spring,
opening to vivid periwinkle blue, star-shaped flowers. They are larger
than the species and are borne in clusters at the ends of each stem.
The bright green, compact foliage forms the perfect background for the
delightful blossoms and then turns a rich shade of yellow in fall.
Amsonia adds a billowy, finely textured element to the landscape. It
grows into a dense mass, much like a small shrub.
'Blue Ice' is a selected seedling from A. tabernaemontana which is native to North America.
Homeowner Growing & Maintenance Tips:
Amsonia thrives in most gardens with little care. It is
low-maintenance, easy to grow and trouble-free. Plant it in full sun or
partial shade and moist soil of average fertility. If grown in too much
shade or very rich soil, its habit will be open and floppy. This plant
grows fairly large but it will not need to be divided for many years.
Cutting the stems back to within 6-8" of the ground after flowering
will result in fuller growth.

Artemisia schmidtiana
'Silver Mound'
Silver Mound Artemesia
|
Aptly
named, 'Silver Mound' has soft, feathery foliage and forms a compact,
silky, cushion-like mound. It has many applications in the garden
including: edging, rock gardens, pots, or a filler plant for hot, dry
areas. It has long been one of the most popular silver foliage plants.
'Silver Mound' combines especially well with dark leaved plants such as
Sedum 'Purple Emperor' or with other silver foliage plants like Stachys
'Silver Carpet'.
Homeowner Growing & Maintenance Tips:
An excellent choice for hot, dry sites, Artemisia should be grown in
very well-drained soil and full sun. To avoid "melting out", it should
be grown in poor soil and trimmed back in late spring. This plant tends
to open up in the center during hot summers, so it is best grown north
of zone 7. 'Silver Mound' rarely needs dividing and should be left
undisturbed.
Grower Cultural Tips:
Cut back hard if the foliage opens up in the center. Prefers being grown on the 'hungry' side. Propagate by stem cuttings.

Astilbe 'Elisabeth van Veen'
Astilbe-Japanese |
• Vibrant raspberry-lilac plumes
• Blooms in early summer
• Mid-green foliage with a reddish tinge
• An excellent new introduction from Holland
A member of Astilbe japonica (Japanese Astilbe). A species
characterized by an early bloom time and glossy green leaves often
tinged with red. Flowers are produced in dense, pyramidal clusters.
Homeowner Growing & Maintenance Tips:
Astilbes are long-lived perennials that are most comfortable when grown
in rich soil and light shade to filtered sun. They will grow in full
shade, but will not bloom as prolifically there. Though they are easy
to grow, Astilbes have one critical requirement--lots of water. Plants
must have consistently moist soil; dryness leads to a quick demise,
especially in sun. Increase watering as the foliage emerges and the
plumes mature. If the soil dries out, the leaves will develop brown,
crispy margins and will begin to drop. Fertilize Astilbes in late
spring before flowering starts. Wait to cut back the old foliage until
spring; it will help protect the plant from winter damage. In the
spring, if the crown has risen above soil level, gently press it back
into the ground and apply some organic matter around the plant. Plants
should be divided in early spring every 3-4 years to maintain vigor.
Grower Cultural Tips:
Larger 2 eye Astilbe can be potted in a gallon size container. The
small 1-2 eye cultivars can be potted in a 2-3 quart container. Use a
commercial mix that has incorporated a lot to moderate level of slow
release fertilizer or continually feed at every watering with 150 ppm N
using a general all purpose water soluable fertilizer such as 20-10-20
or 15-5-15. Begin to grow plant cool at 55 to 60 degree for the first
week. Increase temperatures to speed flowering or lower temperature to
delay flowering. Depending on the cultivar, bloom time varies from 6-12
weeks. The most critical growing aspect with Astilbe is water. Astilbe
require consistently moist soil for optimum performance. Plants should
never dry out. Light shading (30% shade cloth) will help reduce stress.

Astilbe 'Fanal'
Astilbe-Hybrid
|
• Bright red plumes are presented in upright spires
• Blooms in early summer; one of the earliest reds to bloom
• Foliage is mahogany red in spring, turning green by summer
• One of the most popular reds; a vigorous grower
A member of Astilbe x arendsii (Hybrid Astilbe/False Spirea). A group
of hybrids developed by famed German nurseryman George Arends. Includes
crosses between A. chinensis var. davidii with A. astilboides, A.
japonica, and A. thunbergii. The resulting hybrids comprise over 95% of
all Astilbe sold in the USA.

Astilbe 'Peach Blossom'
Astilbe-Japanese
|
• Delicate peach flowers with a hint of pink
• Plumes are full and lend a frothy appearance to the clump
• Blooms in early summer
• Glossy, green foliage
A member of Astilbe japonica (Japanese Astilbe). A species

Aster novae-angliae 'Purple Dome'
Aster-New England
|
Appearing
as masses of solid royal purple from late summer into fall, these
asters form wonderfully compact, rounded mounds. They are terrific
accents for fall blooming grasses and the changing colors of the trees.
Try cutting a few of the tall, flowering stems for a fresh
bouquet--bring the outdoors in.
Asters are native to North America and are generally very easy to grow.
Homeowner Growing & Maintenance Tips:
Asters perform best in rich, evenly moist soil and full sun. Give them
lots of room to grow; good air circulation will help to prevent powdery
mildew. Though this cultivar has a bushy, compact habit, it may still
require staking. To promote dense growth that is less likely to flop,
pinch plants back from late spring until July 4th. Plants should be
divided every couple of years in the spring to maintain their health
and vigor.

Baptisia Starlite Prairieblues TM (x bicolor 'Starlite') PPAF
False Indigo
|
This
beautiful new native cultivar is a selection from a controlled cross of
B. australis x bracteata made by Dr. Jim Ault of the Chicago Botanic
Garden.
One of the earliest Baptisia to bloom, this plant produces very
impressive 24 inch long flower spikes with densely spaced vivid violet
buds and cool periwinkle flowers with butter cream keels in late spring
to early summer. The spikes extend well-above the attractive blue-green
foliage and tend to arch gracefully outward as they age.
In fall, the seed pods turn charcoal black and make an interesting addition to fall bouquets.
Starlite Prairieblues™ has a vase-shaped habit when it is young,
maturing into a broadly rounded shrub-like plant. It is reportedly
quick to mature compared to other Baptisias.
Baptisia is easy to grow and will thrive with little maintenance. There
are many potential applications in the landscape including meadow
plantings, as a backdrop in borders, or as a specimen. Plants are very
long-lived once established.
Tantalizing Trivia: Baptisia australis was the first ever subsidized agricultural crop in America.
Homeowner Growing & Maintenance Tips:
Baptisia grows best in full sun, though it tolerates light shade. If
grown in too much shade, plants may require staking. Baptisia is easily
grown in poor to average soil that is well-drained. Once established,
it is moderately drought tolerant because of its tough, deep taproot.
This perennial native may take a couple of seasons to become
established, but is very long-lived once mature. Avoid disturbing
established clumps.

Coreopsis verticillata 'Moonbeam'
Coreopsis-Threadleaf
|
1992
Perennial Plant Association Plant of the Year. Ever-popular and a
classic perennial, C. 'Moonbeam' is an excellent performer with bright
lemon-yellow flowers produced in profusion from early through late
summer. The airy clumps of fine, needle-like foliage on upright stems
add a nice fine texture element to the landscape.
Coreopsis is one of the easiest perennials to maintain and is a good
choice for beginners. It compliments nearly every other plant in the
garden. The verticillata species is particularly long-lived, has a
longer flowering time, and demonstrates better drought tolerance than
others in the genus.
Homeowner Growing & Maintenance Tips:
Coreopsis is native to North America. Therefore, it is easy to grow,
thriving in any well-drained soil and full sun. Once established, it is
rather drought tolerant. It can be propagated either by seed or by
division every few years in spring or fall.

Dicentra spectabilis
Bleeding Heart-Old-Fashioned
|
A
classic charmer! One of the oldest but still irreplacable perennials in
cultivation. Old-fashioned Bleeding Hearts form large, bushy clumps of
powdery-green foliage comprised of cut or lobed leaves on fleshy stems.
In late spring, chains of puffy heart-shaped flowers with rose-pink
petals and white tips dangle beneath the arching, leafless stems. These
racemes make delightful additions to fresh bouquets, lasting about 2
weeks in a vase. In cooler climates with adequate moisture, the bloom
time may be extended into early summer.
After putting on this fantastic display, Old-Fashioned Bleeding Hearts
usually go dormant until the following spring. However, if plants are
kept well-watered during the spring, dormancy may be delayed until late
summer or early fall. Other bushy perennials, such as Hosta, Geranium,
or Sedge, should be planted nearby to fill in the resulting gaps.
Homeowner Growing & Maintenance Tips:
Dicentra is most at home in woodland settings. It likes rich, loose
soil that is evenly moist but also well-drained. At planting time, add
lots of compost, humus, or peat moss to the soil to enhance its water
retention capabilities. Plants will not grow well in heavy clay soils.
Dicentra should be planted in locations that are protected from high
winds and early frosts, such as the edges of woodlands or on the north
or east sides of buildings. It may be propagated by division in either
spring or fall, taking great care to keep the fleshy roots intact when
transplanting. If spent flowers are not removed, small pods develop and
drop their seeds when mature and dry. If these seeds are left
undisturbed, they will germinate the following spring. The resulting
plantlets are easy to transplant while they are still small.

Dicentra spectabilis 'Alba'
Bleeding Heart-Old Fashioned
|
Every
bit as charming as the pink form, D. s. 'Alba' forms large, bushy
clumps of powdery-light green foliage comprised of cut or lobed leaves
on fleshy stems. In late spring, chains of puffy, white, heart-shaped
flowers dangle beneath the arching, leafless stems. These racemes make
delightful additions to fresh bouquets, lasting about 2 weeks in a
vase. In cooler climates with adequate moisture, the bloom time may be
extended into early summer.
After putting on this fantastic display, Old-Fashioned Bleeding Hearts
usually go dormant until the following spring. However, if plants are
kept well-watered during the spring, dormancy may be delayed until late

Echinacea purpurea 'Pink Double Delight' PP18803
Coneflower
|
This
brand new Echinacea has flowers that are similar to 'Razzmatazz' but
has a shorter, more compact habit. A profusion of true bright pink,
pompon-like flowers which measure about 3" across are produced on
strong, well-branched stems from mid through late summer. The flowers
are long-lasting, turning lavender pink as they age. This new selection
comes from the breeding work of AB Cultivars in The Netherlands.
Praised for their cheerful brightly colored flowers, coneflowers are a
mainstay in today's garden. Be sure to leave some spent blooms on the
plants in the fall because their seeds provide winter food for finches
and other birds. The dried seed heads also provide architectural
interest in the winter.
FUN FACT: The word "echinacea" comes from the Greek word "echinos"
meaning "hedgehog", referring to the flower's spiky central cone.
Homeowner Growing & Maintenance Tips:
Echinacea purpurea is a wildflower native to the eastern United States
and is well-adapted to survive the hot, windy conditions typical of
that region. If properly cared for, they will form attractive colonies
and will live for many years. Coneflowers like it sunny and hot. Though
they will tolerate light shade, fewer flowers will be produced and the
plants will be weakened. Light, loamy soils are best but coneflowers
will grow in any well-drained soil. Once established, they are quite
drought tolerant.

Echinacea purpurea Prairie Splendor™
Coneflower-Purple
|
Unanimously
voted in as a 2007 Fleuroselect Gold Medal winner! This is the first
Echinacea to bloom 100% the first year from seed! It was introduced by
S&G Flowers.
Prairie Splendor™ boasts and earlier bloom time (up to 2 weeks earlier
than other varieties) and an extended flowering period from late June
to the first frost. The 4-6 inch wide, rose pink flowers are presented
atop compact, well-branched plants. This variety is relatively short
for an Echinacea, measuring in around 2 feet tall.
Praised for their large, daisy-like flowers which appear from midsummer
thru fall, after many other perennials have finished blooming,
Coneflowers are a mainstay in today's garden. If deadheaded, the bloom
cycle will be extended. However, some spent blooms should be left on
the plants in fall because their seeds provide winter food for finches
and other birds. The dried seed heads also provide architectural
interest in the winter.

Gaillardia 'Fanfare' PP15892
Blanket Flower
|
This
fantastic new introduction is one of the best new flowering perennials
we've seen in recent years. Making quite a dramatic statement, the
upward-facing, scarlet flowers flare out like trumpets with bright
yellow at the ends, creating a vivid medley of color. Its high-powered
flowering performance starts in early summer and continues into fall.
This cultivar has an especially neat mounded form. A sure-fire winner
for containers, they are long-lasting cut flowers too!
These perennials require little care once established. They are heat
tolerant and actually prefer to be grown in poorer soils. They get
their name from the manner in which they used to blanket North American
prairies with their blooms. They can still be found in fields and along
roadsides in the prairie region and into the Rockies.
Homeowner Growing & Maintenance Tips:
Gaillardia requires full sun and well-drained soil in order to prosper.
Given too much shade, the plants tend to flop over. Though they will
perform best in moist soils, they are highly drought tolerant. Do not
enrich the soil with compost or other rich ingrediants when planting
this perennial. It does best in poor, loose soils and does not tolerate
heavy clay. Plants may be divided every 2-3 years in either spring or
fall and are also easily grown from seed. Deadheading spent blooms will
prolong the bloom time.

Gypsophila paniculata 'Perfecta'
Baby's Breath
|
Relatively
large, double white flowers float like wispy white clouds in early to
midsummer, a couple of weeks later than the other varieties. If
deadheaded, Gypsophila is likely to rebloom in early fall. This
cultivar is similar to 'Bristol Fairy' but is a bit more robust.
Baby's Breath has long been valued as a filler plant in perennial
border gardens and also as a long-lasting cut flower. Its broad habit
makes this plant the perfect cover up for dying bulb foliage or for
perennials, such as poppies or bleeding hearts, that go dormant in
summer. Baby's Breath also makes an excellent dried flower.
'Perfecta' is propagated by tissue culture and is a first generation
plant. Plants produced IN VITRO, by tissue culture methods result in
consistent and vigorous plant growth, thick, healthy stems and superior
flowering performance.
Homeowner Growing & Maintenance Tips:
Baby's Breath should be grown in full sun and slightly alkaline soil.
This can be accomplished by adding lime to the soil at the time of
planting if the original soil is acidic. Good drainage is essential to
the health of this plant. Division is not recommended as a way to
propagate Gypsophila because the large, fleshy roots it produces are
easily damaged and should not be disturbed. Plants should be trimmed
back in spring rather than fall.
Grower Cultural Tips:
Prefers a slightly alkaline soil with good drainage.

Hemerocallis 'Stella de Oro'
Daylily
|
• The world's most popular daylily!
• 2.75", bright gold complete self with mild pie crust edging and a subtle fragrance
• Blooms from early to midsummer, followed by waves
of rebloom into early fall (Reblooms best if plants are deadheaded)
• Extended bloom--flowers last at least 16 hrs. each
• Performs superbly in the landscape; great for edging
• Diploid (Jablonski '75)
• Awards: DFM & HM '79, AM '82, SSM '85
Daylilies can survive many harsh conditions that other plants cannot
including: polluted city environments, slopes, poor and dry soils, near
pavement that is salted in winter, and under Black Walnut trees (not
affected by juglone).
Homeowner Growing & Maintenance Tips:
Daylilies are some of the easiest perennials to grow and are a good
choice for any gardener, from the beginner to the professional. These
are tough, adaptable plants that will grow in any soil, from normal to
slightly wet to dry. Older varieties are able to bloom if planted in
partial shade, but most of the newer introductions need full sun for
best performance. Likewise, older varieties tend to spread more rapidly
than the newer hybrids. All varieties can be divided every 3-4 years by
digging up the entire clump and dividing it into smaller pieces with a
minimum of 3 eyes each. This can be done in either spring or fall.
Plants should be deadheaded for cosmetic purposes, but in most cases
this will not extend the bloom time.

Heuchera 'Caramel' PP16560
Coral Bells
|
The
first in a group of H. villosa hybrids from Thierry Delabroye of
France, discovered by his wife, Sandrine. 'Caramel' is a robust grower
with fuzzy, bright yellow-orange leaves and purple-red undersides. It
has much brighter coloration than H. 'Amber Waves' and has a fabulous
compact habit, forming a tight mound. It looks great in containers or
as edging.
This plant is a Heuchera villosa hybrid. The villosa species is a
large, late blooming type that exhibits an increased tolerance of high
heat and humidity over other species. Most produce cream flowers in
midsummer, though they are grown more for their fantastic foliage. H.
villosa is native to the southeastern United States.
Coral bells are easy to grow and blend easily with most other
perennials in the landscape. Because of their low, mounding habit, they
are often used as edging along paths or in containers. Try cutting a
few of the tall flower scapes for fresh bouquets.
Homeowner Growing & Maintenance Tips:
Heucheras are easy perennials to grow and fit nicely in the front of
any border, rock garden, or container. They grow most vigorously and
have the stongest colors when grown in partial shade (preferably
afternoon shade). They can also be grown in full shade but their growth
rate will be very slow. Some varieties can withstand full sun in
northern climates if they have consistant moisture, but their colors
tend to fade with the intensity of the sun. The soil should be amended
with organic matter prior to planting. It should also have good
drainage and a neutral pH. Heucheras are evergreen in areas with mild
winters. If properly sited out of the way of winter winds and with
reliable snow cover, gardeners in northern regions may also find their
heucheras acting as evergreens. If the plant looks tattered by early
spring, shear off any damaged leaves to make room for the vibrant new
foliage which will fill in quickly. Heucheras can be grown under Black
Walnut trees because they are resistant to the toxin Juglone which the
trees emit from their roots. Heucheras are also salt tolerant. They are
useful in the north along pathways which are salted in winter or for
people gardening in coastal regions. Occasionally in northern regions,
heucheras have a tendancy to heave out of the ground because of the
freeze/thaw cycle. To combat heaving, add an extra layer of compost
around the plant's roots in the fall. In the spring, if the plants have
heaved at all, the new roots will grow into the fresh new layer of
compost.
Grower Cultural Tips:
Start dry until growth starts then keep moist. Prefers a cool start.

Heuchera 'Citronelle' PP17934
Coral Bells
|
'Citronelle'
is a robust hybrid with citron yellow leaves and silver undersides.
When planted in heavier shade, the leaves will be more chartreuse.
Since the leaves are so light in color, this variety appreciates more
shade than some of the other villosa hybrids.
'Citronelle' is a sport of the popular 'Caramel' and has the same great compact habit. It is from Thierry Delabroye of France.
This plant is a Heuchera villosa hybrid. The villosa species is a
large, late blooming type that exhibits an increased tolerance of high
heat and humidity over other species. Most produce cream flowers in
midsummer, though they are grown more for their fantastic foliage. H.
villosa is native to the southeastern United States.
Coral bells are easy to grow and blend easily with most other

are often used as edging along paths or in containers. Try cutting a
few of the tall flower scapes for fresh bouquets.
Homeowner Growing & Maintenance Tips:
Heucheras are easy perennials to grow and fit nicely in the front of
any border, rock garden, or container. They grow most vigorously and
have the stongest colors when grown in partial shade (preferably
afternoon shade). They can also be grown in full shade but their growth
rate will be very slow. Some varieties can withstand full sun in
northern climates if they have consistant moisture, but their colors
tend to fade with the intensity of the sun. The soil should be amended
with organic matter prior to planting. It should also have good
drainage and a neutral pH. Heucheras are evergreen in areas with mild
winters. If properly sited out of the way of winter winds and with
reliable snow cover, gardeners in northern regions may also find their
heucheras acting as evergreens. If the plant looks tattered by early
spring, shear off any damaged leaves to make room for the vibrant new
foliage which will fill in quickly. Heucheras can be grown under Black
Walnut trees because they are resistant to the toxin Juglone which the
trees emit from their roots. Heucheras are also salt tolerant. They are
useful in the north along pathways which are salted in winter or for
people gardening in coastal regions. Occasionally in northern regions,
heucheras have a tendancy to heave out of the ground because of the
freeze/thaw cycle. To combat heaving, add an extra layer of compost
around the plant's roots in the fall. In the spring, if the plants have
heaved at all, the new roots will grow into the fresh new layer of
compost.

Hibiscus 'Fantasia' PP11853
Rose Mallow
|
Huge,
dinner plate sized 8-9 inch wide flowers sit atop compact, mounded,
shrub-like plants from mid to late summer. Each successive spring will
bring larger flowers. This selection produces great numbers of ruffled,
rose-pink flowers with a red eye.
The distinctively lobed, maple-like leaves are of heavy substance and
add to the substantial look of this plant. It's hard to believe this
tropical-looking beauty is hardy to zone 4! An introduction from the
Fleming Brothers.
Homeowner Growing & Maintenance Tips:
Hibiscus love the sun and need moist, well-drained soil. Keeping these
plants watered will result in larger flowers and lush foliage.
Deadheading may prolong the bloom period. It is best to plant Hibiscus
in the garden before the heat of the summer arrives, and should be
heavily mulched the first winter. In spring, cut back any remaining
stems before new growth appears. Be advised that this species is always
one of the last to emerge in spring. Its vigorous growth rate more than
makes up for this late start, however. Japanese beetles find these
plants especially delicious.
Grower Cultural Tips:
Grows better at 70-75 Degrees. Needs long day to break dormancy (14 hrs). Start dry until growth stars then keep moist.

Hibiscus moscheutos 'Pink Elephant' PPAF
Rose Mallow
|
Aptly
named, this outstanding new cultivar has the largest flowers we've ever
seen on a Hardy Hibiscus! They open up flat to a whopping 1 foot wide!
The medium pink blossoms have beautifully ruffled, overlapping petals
and a deep red eye. They are produced from mid through late summer and
in warmer zones the plant may rebloom again in early fall, an unusual
trait for Hibiscus. From Tom Miksich of Indiana.

Hosta 'Blue Angel'
Hosta
|
• Gigantic, heart-shaped, blue-green leaves are of heavy substance and are very slug resistant
• Leaf petioles stand upright holding the leaves
horizontally, then cascade downward forming a beautiful mound of foliage
• White flowers are held attractively above the foliage on 48" scapes in midsummer
• Awards: Lucille Simpers Award, '90, '97, and '98;
Best Green Hosta Award, '91; Best Blue Leaf Award, '94; Best Blue Hosta
Award, '00, '01, and '04
• Registered by Aden
Hostas are exceedingly popular perennials in today's gardens due to
their versatility in the landscape. Their subtle colors, tall flower
scapes, and broad, coarse leaves fill a niche in garden designs that
few other plants can achieve. Their large leaves provide excellent
coverage for dying bulb foliage. Hostas also grow well in city
environments where the air may be polluted by car exhaust, etc.
Homeowner Growing & Maintenance Tips:
Hostas grow best in moist, well-drained, highly organic soils with a pH
between 5.5 and 7.5. Sandy loam is better than clay because it provides
more aeration for the roots. High-filtered or dappled sunlight is
necessary for clean, healthy growth. Morning sun is tolerable and will
help to intensify the leaf colors, but hot afternoon sun is usually
deadly to hostas. They are most at home in shady, woodland settings and
often work well as specimen or edging plants. Hostas are very easy to
propagate through division. This can be done at any time during the
growing season with little or no affect on the growth of the parent
plant. Since each division should have at least 3 eyes, plants should
be allowed to mature for several years before being divided. Especially
in northern zones, hostas should be mulched with a layer of finely
shredded organic material to prevent heaving in the winter. Mulch is
beneficial because it retains moisture around the plant's roots, but it
is also the ideal place for slugs to hide. Watch for holes in the
center of the leaves. If they are present, so are slugs. Applying a
slug bait in early spring when new shoots are beginning to emerge will
help to reduce the slug population. After a few years when plants are
firmly established, the mulch can be removed completely, which should
eliminate the slug problem altogether. Also be sure to clean all hosta
foliage out of the garden in early winter after the plants have gone
dormant. By doing so, you will be ridding the area of the eggs of slugs
and other leaf-eating insects.

Leucanthemum superbum 'Amelia'
Shasta Daisy
|
In
a seven year trial of 36 varieties of Shasta Daisy led by Richard Hawke
of the Chicago Botanic Garden, the honor of a 5 star excellent rating
was bestowed upon only two varieties of L. superbum: 'Becky' and
'Amelia'.
You've been growing 'Becky' for years; now try her fellow award winner!
CBG selected 'Amelia' for its consistently healthy disposition with
heavy flowering production and a robust habit. It consistently produced
the largest flowers of all varieties in the trial.
Single, white blossoms with a golden yellow center measure a whopping
five inches across and bloom from early summer into late summer. Since
the plants are from seed, their height will vary slightly but will
average 40".
Shasta Daisies are all-time favorites for the perennial border. The
cheery flowers begin to appear in late spring and continue on for
several months if faithfully deadheaded. Shastas mix so effortlessly
with other perennials that no garden should be without them!
Homeowner Growing & Maintenance Tips:
Leucanthemums require full sun and well-drained soil to be at their
best. Winter drainage is especially important; planting in raised beds
will help to provide these conditions. Shastas make good perennials for
Southern gardens, though partial shade is recommended in the warmest
zones. Division can be done in either spring or fall, and is
recommended due to this perennial's tendancy to be short-lived.

Liatris spicata 'Floristan White'
Gayfeather
|
Multiple
wands of creamy white flowers open from top to bottom beginning in
early summer. Narrow, opposite leaves are up to 10 inches long at the
base of the plant and decrease in length up the stems.
All together, Liatris is a very strong vertical accent for the garden.
It is a staple item for cutting gardens; it adds a bright, vertical
element to bouquets.
Homeowner Growing & Maintenance Tips:
L. spicata prefers more moisture than other members of the Liatris
family, and thrives in well-drained soil in full sun. It is a suitable
choice for southern gardens since it is very tolerant of hot summers.
The roots of this genus are tuberous, and they may be lifted every few
years and divided. When doing so, use a sharp knife, allow at least one
eye per division, and dust the newly cut ends with a fungicidal powder
before replanting.

Lupinus Russell Hybrids-Mixed
Lupine
|
Russell
Hybrids-Mixed is a mixed seed strain of lupines that includes a
colorful mix of blue, purple, yellow, red, and pink flowers. They are
about a foot taller than the Popsicle Series lupines and bloom about 2
weeks later.
Lupines really come into their own during warm, sunny days and cool
nights and look especially lovely when grown in masses with similar
varieties. A memorable sight for any garden lover, these beautiful
plants grow into well-established clumps, with several stems rising up
out of a single base. A bouquet of Lupines has no equal!
Homeowner Growing & Maintenance Tips:
Grow Lupines in full sun or light shade. They require rich organic soil
with slight acidity and good drainage. They thrive in cool climates,
and find it difficult to survive in areas with extremely hot summers.
Applying mulch around the root zone will help to keep the roots cool
and will protect them over the winter. Deadheading spent flowers will
prolong the bloom time, as well as rejuvenate the plants in cool areas.
These plants tend to attract aphids, but this can be avoided by cutting
them back periodically, or spraying for the pests before they become a
problem.

Homeowner Growing & Maintenance Tips:
The ideal plant for hot, dry climates! Russian Sage is classified as a
subshrub or woody perennial. It performs very well in full sun and any
well-drained soil. Average to dry moisture levels are ideal, and few
pests bother this plant. If pruning is necessary, do so in Spring when
new growth appears. Prune back to just above the lowest bud.

Phlox arendsii 'Babyface'
Phlox-Arends
|
Sweetly
fragrant, baby pink blooms with sizeable rosy-red eyes are produced
prolifically from mid thru late summer. They make excellent cut flowers
and also attract butterflies.
Phlox arendsii is the result of crosses between P. divaricata and P.
paniculata. It is intermediate in height and very floriferous.
Homeowner Growing & Maintenance Tips:
Phlox arendsii is unequaled for showy blooms over a long period
throughout the summer. Though they are some of the most popular
perennials available, they do require some maintenance to sustain their
health and vigor. Arends Phlox grows best in rich, moist soil in full
sun. It will thrive with bi-monthly fertilizing and consistant moisture
levels. Overhead watering should be avoided since some varieties of
Phlox are susceptible to powdery mildew. This can be avoided or
diminished by providing ample air circulation around the plants and by
thinning them out periodically. Deadheading will prolong bloom time and
prevent self-seeding.

Rudbeckia fulgida 'Goldsturm'
Black-Eyed Susan
|
Black
Eyed Susans are one of the most popular perennials available today,
having earned the prestigious Perennial Plant of the Year Award in
1999.
Plants have a long season of bloom and a sturdy, upright habit. The
gold daisy-like flowers have a distinct dark brown central cone and are
held on branching stems. Do not deadhead these cones if you want winter
interest since the black seed heads remain attractive throughout the
winter and the seeds provide a source of food for small birds.
A classic garden combination includes upright Sedum 'Autumn Joy' and
Perovskia atriplicifolia. It is an excellent perennial for providing
color in late summer and is especially showy in mass plantings.
Homeowner Growing & Maintenance Tips:
Rudbeckias like full sun, but they also will do well in partial shade.
Plant them in well-drained, not overly rich soil. Remove spent flowers
in order to stimulate continuous bloom. Plants will self-seed. If this
is not desired, cut the plants back in fall. Rudbeckias are very easy
to divide in the spring. They also make great cut flowers.

Salvia 'Eveline' PP14905, CPBR2674
Salvia-Perennial
|
This
showy new Salvia was selected by renowned plantsman Piet Oudolf of The
Netherlands for its superior flowers and upright, bushy habit. It is
very floriferous in early summer and may rebloom if cut back.
Large, two-toned light pink and purple flowers are held on tall spikes
above a basal rosette of green foliage. They add great texture and
fragrance to both fresh and dried bouquets.
This is a clump forming perennial with oblong leaves which are aromatic when crushed. Use it in containers, beds, and borders.
Salvia 'Eveline' PP14905 was introduced through Future Plants.
Homeowner Growing & Maintenance Tips:
Salvia is easy to grow in almost any climate. Though it is drought
tolerant, it will bloom better with regular watering. Deadheading
encourages a longer bloom time. If plants get leggy during the season,
cut them all the way back to the newly developed foliage. If cut back,
plants may rebloom in fall but often the flowers are fewer and smaller.

Sedum 'Autumn Joy' ('Herbstfreude')
Stonecrop-Autumn
|
One
of the most popular perennials on the market today. This hardy, upright
selection sports light green leaves and deep rose flowers which age to
a beautiful bronze.
Tall, upright sedums form substantial clumps of foliage which can be
substituted for shrubs in the landscape. Their stout, sturdy stems
support the massive flower heads which develop in summer and burst into
bloom in fall. If left standing, they provide winter interest and food
for birds.
Homeowner Growing & Maintenance Tips:
Sedum is one of the most popular perennials grown in American gardens
because it is very easy to grow and hardy in most areas of the country.
Because of its thick, succulent leaves which can store water, sedum is
drought tolerant. It should be sited in average to poor soil that is
well-drained. Plants grown in rich soil tend to be lanky and open. Most
varieties should be grown in full sun to light shade. The lower growing
types, however, will survive in partial shade. Divide sedum every 3-4
years to maintain its compact growth habit. Older plants tend to split
in the center if they have not been divided. Pinching the taller
varieties back by half in early summer will also help prevent them from
splitting. This plant is not usually bothered by pests or diseases. The
seed heads of the taller varieties provide excellent winter interest
and food for birds. Remove them in spring when the new growth begins to
show.

Stachys monieri 'Hummelo'
Betony
|
Unlike
Stachys byzantina (Lamb's Ear), this species forms large, rounded
clumps of green, long and narrow, textured leaves. It is lovely even
when it's not in bloom. In midsummer, sturdy spikes of lavender-rose
flowers shoot up through the foliage, putting on quite a display. Since
it is relatively unknown to many gardeners, people always gasp in awe
of this plant when it is in bloom. It makes a unique addition to any
sunny border!
Stachys m. 'Hummello' received the highest rating out of 22 stachys
studied in the Plant Evaluation Trials at the Chicago Botanic Gardens.
The trial was run from 1998-2004 by Richard G. Hawke. Both 'Helen von
Stein' (aka 'Big Ears') and 'Silver Carpet' also received very high
scores.
Homeowner Growing & Maintenance Tips:
Stachys grows best in full sun but will also tolerate partial shade.
Good drainage is essential for this plant. Divide every 3-4 years in
spring or more frequently if plants become woody in the center.

Veronica 'Giles van Hees'
Speedwell-Spike
|
A
dwarf veronica perfect for the front of the border or in containers.
This variety looks much like its larger cousins, but is shorter. The
dark green foliage forms a nice mound topped by bright pink flower
spikes whose sweet nectar attracts butterflies. It is extremely
long-flowering beginning in midsummer and is easy to grow.
Homeowner Growing & Maintenance Tips:
This perennial is tolerant of a wide range of well-drained soil types.
Amending soils, especially very heavy and light types, with generous
amounts of organic matter will result in improved performance. Although
tolerant of partial shade, it will flower better in full sun.
Deadheading will promote additional blooms.
