Some Larger Shrubs to Consider Planting
March 2, 2000
Thinking of adding a large shrub or two to the landscape this season?
There are many to choose from. Large shrubs may provide a background or
screen, may be an interesting focal point, provide cover for birds, and
may produce attractive flowers and even fruit. Here's a review a
few of the more popular choices for northern Illinois landscapes.
Viburnums are a popular, versatile group of large shrubs ideal for background
or screen plantings in sun or semi-shade locations. Most will flower and
produce fruit that is usually attractive to wildlife. Among the popular
larger viburnum species are wayfaringtree, nannyberry, arrowwood, and
American cranberrybush viburnum species.
Dogwoods are another group of popular larger shrubs. Redosier dogwood
(Cornus sericea) is a spreading shrub that tolerates wet and poorly
drained soils. Twigs are red, and need to be pruned on a regular basis
to maintain attractive color. Another good choice is gray dogwood (Cornus
racemosa), which is a very adaptable shrub good for screen or natural
type plantings. Corneliancherry dogwood (Cornus mas) can become
very large (15 feet) and may grow out of bounds. Yellow flowers in early
spring are popular, but may be damaged in severe winters.
Discussion of large flowering shrubs has to include lilacs. Fragrant
purple, pink, or white flowers make this shrub a longtime favorite. Many
cultivars are available though area nurseries. Keep in mind that it's
best to prune lilacs on a regular basis to avoid older, woody trunks that
attract insect borers and also decline in flowering.
Serviceberry (Amelanchier species) is an adaptable shrub well
suited for wooded areas. This shrub tolerates shade and alkaline soils.
White flowers will yield edible purple fruits, and the foliage gets yellow
or orange fall color. Finally, common Witchhazel (Hamamelis virginiana) is a good natural
background planting for larger landscape settings. This shrub tolerates
poor soil and also has a spreading growth habit. Yellow flowers appear
in October. |
