They say nothing in life is a sure thing except death and taxes.
We beg to differ.
The arrival of new plants each spring is equally certain and far
more pleasant.
Even if we didn't have 3 gazillion plant breeders and collectors
to bring us the newest and coolest, we'd still get a parade of
plants each year. Without any help, nature serves us surprises
through natural selection and mutants.
As you walk the aisles of your garden center, you may feel as if
every combination imaginable has already been developed. Such an
idea! How would we cope without the knowledge that not only
spring comes every year, but so do the new perennials?
New may not necessarily be better, but it sure is exciting.
Just like spring.
Acanthus mollis 'Tasmanian Angel' (variegated bear's breeches):
Judging from the Northwest Flower & Garden Show, the first
variegated bear's breeches is set to take gardeners by storm.
Even for those of us who don't like Acanthus, this baby is a
must to bring brightness and unusual texture to shady gardens.
Just enough white variegation makes it so much more interesting
than the plain green ones. Tall stalks of pink and cream flowers
appear in late summer. Give it moist but well-drained soil.
Stock is still fairly limited, so prices will be high. Forms
2-by-2-foot clump in three years. Zone 4. (Terra Nova, Xera
Plants)
Anemanthele lessoniana (wind grass, gossamer grass): A very
pretty ornamental grass from New Zealand. Green under normal
circumstances, it colors up to sunset shades in winter or if
drought-stressed in summer. Throws up feathery flowers in late
summer. Totally worthy of a place in your garden -- if you can
find it. Can take some shade, but best color in full sun. Gets
about 3 feet tall, 4 feet wide. Zone 8. (Rare Plant Research)
Baptisia x variicolor 'Twilite Prairieblues' (false indigo):
Introduced after six years of development by the Chicago Botanic
Garden, this new Baptisia has the benefit of strong stems that
stay upright even in strong winds. If that's not enough, this
member of the pea family cranks out the flowers (violet with
yellow bottom petals) -- as many as 100 spikes a season, which
lasts from mid-May through June. Full sun. 3-5 feet tall, 4-5
feet wide. Zone 4. (Log House)
Coreopsis 'Jethro Tull' (tickseed): We're not sure if this is
named after the rock band or the 18th-century agriculturist, but
we'll take it either way. A two-month (June-August) blooming
season offers plenty of time to enjoy the unusual flowers with
fluted yellow petals. Deadhead to keep plant blooming. Full sun.
Wider (18 inches) than tall (12-15 inches), this compact
Coreopsis makes a good ground cover. (Skagit Gardens)
Cotyledon 'Chalkstick Fingers': As we move into the Year of
Succulents (our prediction), this pretty thing from South Africa
will find a home in many a garden. Spiky, bluish-silver foliage
nicely sets off the pink flowers. If planted in a well-drained
southern aspect and protected in winter, it can grow into a
small shrub. Full sun. Zone 9. (Rare Plant Research)
Delphinium elatum 'Chocolate': What's your fancy? Dark
chocolate? Milk chocolate? White? Oh, why choose? Have it all
with a new English delphinium in delectable shades of brown and
cream. The eye-candy blooms, some veined, some picoteed or
stippled, some swirled with color, wink from strong, statuesque
stalks up to 8 feet tall. Blooms from June through July. Don't
worry, these treats are calorie-free. Plant in sunny but not
baking-hot spot in rich, well-drained soil. 6-8 feet tall. Zone
3. (Log House exclusive)
Drimia maritima syn. Urginea maritima (sea squill, sea onion):
At the size of a soccer ball, the bulb is dramatic enough. But
wait till you see this Mediterranean giant bloom. The lilylike
foliage dies down as summer wears on, and then a 4- to 5-foot
stalk emerges with hundreds of fragrant, star-shaped white
flowers with prickly white stamens. Plant this puppy and amaze
your friends! Full sun. Zone 9 if grown elevated in a container;
Zone 8 if planted in fast-draining soil. (Available in the
Northwest for the first time at Rare Plant Research's open house
May 19-20.)
Echinacea purpurea 'Green Envy,' Echinacea 'Tiki Torch' and
Echinacea 'Summer Sky': The race for Echinacea supremacy
continues at a fast clip. Can we get enough? Not yet,
apparently. Here are three to hit the market this year that we
think are worth your attention. 'Green Envy' (3-4 feet tall and
wide) takes a cool approach with bright green, rounded petals
with an orange blush near the deep green button cone. Lightly
scented. 'Tiki Torch' (24 inches tall and wide) is the darkest
of the orange offerings and comes complete with a big cone also
tipped with orange. Spicy scent. The newest in the Big Sky
series and the first bicolor coneflower, 'Summer Sky' (30-36
inches tall, 18-24 inches wide) is centered with an orange cone
with light orange petals overlaid with a rose halo. The most
fragrant in the series. Plant all in full sun. Give plenty of
fertilizer and water. All Zone 4. 'Green Envy' (Log House); 'Tiki
Torch' (Terra Nova); 'Summer Sky' (Xera)
Erysimum 'Jenny Brook' (wallflower): Discovered in 2001 on the
west coast of Wales, this charmer can't help but catch your eye.
The clusters of multicolored flowers bloom in pastel shades of
pink, peach and lavender that are so pretty we want to paint our
bedrooms in these colors. Give this hardworking perennial a
prominent spot in the sun because it'll bloom for you from
spring into late fall. 18-24 inches tall. Zone 7. (Log House)
Euphorbia 'Glacier Blue' and 'Shorty' (spurge): Which Euphorbia
will you grow? It would be fun to try them all, but that's a bit
impractical. Instead, focus on two new ones: 'Glacier Blue,' a
compact, icy beauty with cream-edged blue foliage and flower
bracts that echo the foliage and add to the show February
through May. Or 'Shorty,' another, duh, short plant, but this
one with blue-green foliage that softens to a softer green with
red tips in fall. Color intensifies in winter, and bright yellow
flowers appear March through May. 'Glacier Blue' is 12-15 inches
tall, 18 inches wide. 'Shorty' is 15-18 inches tall, 15 inches
wide. Both prefer full sun and are hardy to Zone 7. (Skagit
Gardens)
Gaillardia 'Dakota Reveille' (blanket flower): Sunrise, sunset.
You choose the time of day, and this blanket flower will give
you the colors. A tight center bud starts out an incredible lime
green with red tips before opening into big, round flowers
densely filled with red-throated, trumpet-shaped golden petals.
Compact and mounding habit makes it a great border or container
plant. Long blooming and great for cut flowers. Birds love the
seed heads in fall. Full sun. 20-24 inches tall. Zone 3. (Log
House)
Heuchera 'Midnight Rose' (coral bells): After complaining
bitterly the past couple of years about the number of Heuchera
cultivars on the market, we've decided to shut our yaps. Yes,
there is a reason for a new Heuchera, and the evidence is right
here. We've never seen another like it (and we've seen lots).
The cabernet-colored foliage is speckled and spotted with a
sprightly rose pink. Flowers? Who really cares. But if you must
know, they're insignificant wands of cream. 10 inches tall, 16
inches wide. Sun to part shade. Zone 4. (Terra Nova)
Musa 'Brown's Red' (banana): Not the best name ever, but we can
forgive that after a glimpse at the gorgeousness of this
red-splashed banana. Not exactly hardy, we included it anyway
because, well, just because. Burl Mostel of Rare Plant Research,
which is introducing it to the West Coast, says 'Brown's Red' is
an improvement over Musa zebrina. We say go for it. Excellent
for containers. Full sun. 7 feet tall. Zone 10, but its
relatively short stature makes it far easier to overwinter in
the house than taller cultivars. (Rare Plant Research)
Petasites frigidus var. palmatus 'Golden Palms' (golden
coltsfoot): Want to catch someone's attention? Plant this
moisture-loving ground cover that startles the world when it
sends up 1-foot-wide metallic golden "palms" in early spring.
Give it part sun for best shimmering color. Will be difficult to
find, but persevere and be rewarded. 12 inches tall, spreading.
Zone 6. (Terra Nova)
Salvia nemorosa 'Sensation Rose' (sage): A very hardy new dwarf
salvia that perks up the front of borders or containers. Strong
stems hold really nice rose-pink flowers that attract bees and
butterflies. Full sun. 10-12 inches tall, 12 inches wide. Zone
4. (Skagit Gardens)
