2003 Great Plant Picks
Nancy Tom
It’s great to look at the new plant
picks lists put out by nurseries and growers from near and far.
But some of the most coveted advice gardeners get about plants is
the advice from fellow gardeners. And that’s what makes this
pick list so special.
The Elisabeth C. Miller Botanical Garden was
the private garden of Elisabeth and Pendelton Miller. With stunning
views of Puget Sound, this garden is known for its wide and varied
selection of trees, shrubs, and woodland herbaceous perennials.
In just three acres of gardens are over 3,600 taxa of plant material.
Now the site is in the capable hands of a board of trustees who
want nothing more than to educate Pacific Northwest gardeners about
the plant material which thrives here.
This eliminates a lot of research work on
our part. The list for 2003, like other years, was put together
by nursery professionals, growers, horticulturists, avid gardeners
and landscape and garden designers. Selections are made within three
categories: trees and conifers, shrubs and vines and perennials
and bulbs. You’ll find old favorites and newcomers alike,
so there is something here for everyone and every type of need.
And, it’s accessible on-line at www.greatplantpicks.org.
Don’t miss the separate pages for each plant describing culture,
habit, usage and suitable companion plants. There’s even a
picture. In fact, there’s so much information that comfortable
seating is a must when visiting this website!
Some Sunny Considerations
There are actually plants that grow
in full sun that we can’t grow here! What are they? Some palm
trees, banana trees… think tropical! But we can grow crabapples
and this year there are several on the list: ‘Strawberry Parfait’
with its pink blooms and red fruit would make a welcome spring statement
anywhere. Or, GOLDEN RAINDROPS® Crabapple (Malus transitoria
GOLDEN RAINDROPS®) with its tiny golden fruit will add unusual
fall color while supporting the birds. There is also a fragrant
crabapple, SUGAR TYME®, turning back the clock hands to the
fragrant gardens of yesterday.
Cherry trees also flower in spring and prefer
full sun. Yoshino Cherry (Prunus x yedoensis) was among
the cherry trees planted in Washington D.C. many years ago. On the
Great Plant Picks List is ‘Akebono’ offering pure pink
flowers in early spring and sprightly yellow-orange fall color.
Growing twenty-five to thirty feet tall and spreading twenty-five
to thirty-five feet wide, this tree makes a beautiful lawn specimen.
Another great lawn specimen is the PACIFIC
SUNSET ® Maple (A. truncatum x A. platanoides Warrenred’
P.P. No. 7433). This tree has incredible orange fall color with
medium-sized leaves. Growing to thirty feet tall and with a twenty-five
foot spread, its pyramidal-to-round structure is pleasing, and it
still allows space for low-growing shrubs or perennials. The russet
colors of the PACIFIC SUNSET® foliage and the reddish-orange
fruit of Creeping Taiwan Bramble (Rubus pentalobus) come together
to make a colorful combination while providing for the birds.
To create a completely different feeling while
still using maples, Japanese maples (Acer palmatum) provide
an Asian feel to any landscape. Their delicate but colorful simplicity
has inspired hundreds of Japanese gardens, and here it inspires
gardens for those who delight in texture, form and color while creating
an unassuming ambience. There is a Japanese maple for any location,
even a container. ‘Shaina’ is a layered, but densely-leaved
maple which reaches only three to four feet in height, and that
very slowly. For more spacious sunny locations, there is ‘Ukigumo’
(Acer palmatum ‘Ukigumo’). This tree displays
green leaves which turn flaming red in fall. As its name implies,
‘Orangeola’ produces burgundy red new growth which turns
coppery-red in fall, and, ‘Shishigashira’ begins the
spring with bright green leaves which later turn bright reddish-orange.
Looking beneath these beauties, we might find a David Viburnum (Viburnum
davidii), a staple here which does well in sun or shade and
looks best when massed. After it’s established, this plant
is drought tolerant, its moisture retained in its thick, leathery
leaves. Rhododendron ‘The Hon. Jean Marie de Montague’
thrives in heat and sun. It gets to be about five feet tall in ten
years and will grow larger in time. With its red blooms held in
trusses of up to fourteen blooms at a time, it’s an exuberant
mid-season bloomer and would look well flanking any of these maple
selections. Ilex crenata ‘Convexa’ with its
small evergreen leaves and dark purple black berries is an excellent
foil for the summer blooms of Penstemon ‘Blackbird’,
and Georgia Blue Speedwell (Veronica peduncularis ‘Georgia
Blue’) makes a fine groundcover growing to about four inches
in height and blooming from summer to mid-autumn.
Conifers can be sun worshippers too, and Golden
Japanese Cedar and Plume Japanese Cedar (Cryptomeria japonica
‘Sekkan-sugi’ and Cryptomeria Elegans Group) are rapidly
growing conifers that do best in full sun down to partial shade.
The Plume Japanese Cedar can achieve thirty feet in height and eight
feet in width. In time they can be larger. ‘Sekkan-sugi’
is upright, growing to twenty-five feet tall and more, displaying
dense golden foliage. Paired with park-sized blue-needled giant
sequoia (Sequoiadendron gaganteum ‘Glaucum’)
or, for the modest backyards most of us have, Oriental Spruce (Picea
orientalis) and Himalayan White Birch (Betula utilis var
jacquemontii) in front, a wooded backdrop can easily be created.
The Himalayan White Birch planted in front would add striking vertical
accents from its silvery bark peeling back to reveal burgundy undertones.
Planted beneath might go Minuet Mountain Laurel (Kalmia latifolia
‘Minuet’). This shrub grows to be five to six feet tall
and wide. Like rhododendrons, this shrub is Ericaceous, but its
blooms are like patterned stars, made prominent by the dark back
drop of its evergreen leaves. ‘Minuet’ is slow-growing,
and would be an excellent companion to the deciduous Rhododendron
‘Snowbird’ which grows well in sunny to partially sunny
conditions. ‘Snowbird’ produces sweetly-fragrant spring
blooms, and it’s hardy and stoloniferous. Its medium green
foliage and comfortable height of four feet make it easy to mix
in any number of naturalizing conditions.
The Woodlands
Plants suitable for the woodlands, either to supplement existing
sites or create new ones, are abundant on the list. For magnolia
fans, the Oyama Magnolia (Magnolia sieboldii), is the perfect
woodland tree. Flourishing in humic conditions and flowering heavily
in spring and then lightly all summer long, its white, fragrant
flowers are a delight. Sargent’s Weeping Hemlock (Tsuga
canadensis ‘Pendula’), and the Weeping Katsura
tree (Cercidiphyllum japonicum ‘Morioka Weeping’)
do best in light shade. As weeping trees, the eye is naturally led
to the earth beneath. Variation through foliage and bloom can be
added by planting perennials such as Gold Heart Bleeding Heart (Dicentra
spectabilis ‘Gold Heart’), Sum and Substance Hosta
(Hosta ‘Sum and Substance’), Variegated Gladwyn
Iris (Iris foetidissima ‘Variegata’) and Guinevere
Primrose (Primula ‘Guinevere’). Wood Anemone
(Anemone nemorosa) is a proven groundcover, as well as
one that I have to throw in even though it’s not on the list:
Hepatica (Hepatica nobilis). They’re drought tolerant,
semi-evergreen in our climate and have beautiful white, blue, purple
or pink flowers which bloom in early spring.
The Spring Pea Bush, (Lathyrus vernus),
is a moisture-loving perennial that, while slow to establish, is
tough as nails once it has. A member of the pea family, it offers
about two months of purple-blue blooms. Evergreen here, this perennial
enjoys more light in winter so consider planting under deciduous
trees.
Have fun tiptoeing through the magnolias,
and the viburnums, and the campanulas… I only wish I could
have gotten to all of them! You will not be disappointed.
