SHADE
LOVING PLANTS

One
gardening complaint I hear often is from people who dont think
they have enough sun to grow anything in their yard. They have so
convinced themselves of this that they have given up trying. Perhaps
their heads are filled with visions of zinnias and sunflowers, but
these folks dont realize that they are missing some of the most
beautiful plants in the garden by not familiarizing themselves with
the many types of shade tolerant varieties.
Shade loving plants were among the first flowering vegetation to appear
on earth. Some plants like rhododendron and magnolia are cousins to
those primordial specimens that evolved in the shade of their taller
neighbors.
Ornamental trees are the most prominent plant to provide color in
the landscape. Dogwoods display flower bracts, either white or pink,
in the spring, colorful leaves in fall and berries all winter. In
shade under tall trees, dogwoods and shade perennials can be used
to naturalize a shady area.
SHRUBS AND VINES
There are many shrubs and vines that can bring color to the shade
garden, not only with flowers, but by producing berries in various
hues. Rhododendron species are mainstays for shady areas throughout
much of North America. Although deciduous, azalea provide a burst
of spring color that makes its somewhat ordinary habit the rest of
the year acceptable.
Hydrangea is another reliable shade shrub with long lasting blooms
in summer of white, pink or blue. Flower color is influenced by the
acidity of the soil with more acid soil producing blue flowers and
alkaline soil pink flowers. There are climbing forms that will wind
along walls or around trees.
Most flowering vines are sun lovers but a few will bloom in partial
shade, including some species of clematis and honeysuckle.
HERBACEOUS BLOOMERS
No garden need be without visual impact since there are many shade
loving perennials and annuals that bring color to the shade garden.
Annuals are generally considered to be sun plants, but they can be
successfully grown in dappled light or partial shade. Frequent fertilization
and rich, composted soil will make your plants robust and bloom freely.
Impatiens are a dependable annual favorite of shade gardeners everywhere.
They are available in many shades from white to red, purple and orange.
They bloom vigorously and produces masses of flowers which require
no deadheading. They can be grown in partial sun with plenty of water
and provide large masses of color.
Ageratum is a tidy little plant that blooms profusely and reliably
all season long in the shade garden. There is a tall growing variety
that is perfect for cut flower arrangements. Begonia flowers from
spring through frost with little care and comes in different leaf
colors for foliage variety in the shade.
GROUND COVERS
Some of the most popular and colorful ground covers actually prefer
the shade and perform well in all soil types. Vinca (periwinkle) will
spread in the poorest soil, producing blossoms of white or blue. Heuchera
(coral bells), a low growing perennial, displays unusual veined leaves
with white spiky flowers. Several types of Epimedium (bishops
hat) will blanket even dry shade and produce* yellow blossoms. Although
not specifically a ground cover, hosta can serve to fill in shady
borders and cover foliage from spring flowering bulbs.
UNIQUE QUALITIES
Although there are many diverse types, shade plants share some unique
characteristics that have developed from the difficult conditions
of their evolution. They often must adapt to areas congested with
tree roots, as a result, most shade plant have shallow roots. Even
large rhododendrons have a small and manageable root ball.
Shade lovers are also more sensitive than other plants to moisture
levels in the soil. Many may require a layer of leaf litter or mulch
to keep them from drying out. This trait makes the shade flower garden
fairly low maintenance. In fall, only the heaviest drifts of fallen
leaves need be removed, leaving in place a protective leaf cover.
Many shade loving plants are self-sowing, meaning that if you dont
tidy up too much, you will have a new stock of seedlings to increase
your plantings.
COLORFUL SHADE
Color plays an important role in attracting pollinators to your garden.
Foraging bees respond most to blue and yellow and yellow is among
the commonest color in shade blooming plants. The vivid red of cardinal
flower, a climbing vine, attracts hummingbirds to its droopy blossoms.
Besides attracting pollinators, color plays an important role in the
mood of the garden. Glowing yellow flowers in spring welcome the warmths
return. Pastels and dark leaves cool us in summer and deepen the effect
of shade beneath large trees. White flowers appear brighter in the
shade garden and practically glow in the lower light. The same plant
may produce markedly different color blossoms in shade and sun, so
experiment with some favorites. Because shade softens contrasting
flower colors, try using bolder combinations than you might otherwise
try.
Shade gardening with the right plants is rewarding and produces a
soothing garden atmosphere that is not possible in a sunny, open area.
If areas of your landscape require shade tolerant plants, look forward
to this opportunity to become acquainted with some of the underrated
heroes of the garden.
