Cotoneaster Accents Walls, Covers Slopes
cotoneaster, Cotoneaster horizontalis, is a lovely plant
to consider when you are looking for a plant to cover a bank or
drape over a wall. The stem grows in an interesting fishbone or
herringbone pattern which creates a flat growth and layered effect
that makes it an excellent choice. The plant is also a good selection
for rock gardens or to espalier.
This versatile plant brightens fall and winter with its red berries
that decorate the stiff, spreading branches. It is generally thought
of as semi-evergreen though it sometimes is considered evergreen
or deciduous. The plant grows to a height of about 2 to 3 feet
with a spread of 5 to 8 feet and has a small, fine-textured green
leaf that turns purplish red in fall. In May, it has small, ¼"
diameter, whitish pink blooms.
Cotoneaster horizontalis, widely used in England, is worthy
of more frequent consideration in our landscapes, particularly
for its hardiness and nice features throughout the year. It is
related to apples, pears and hawthorns. This cotoneaster grows
in zones 6, 7 and 8, and tolerates coastal areas. Because of its
sparse root system, plant container-grown plants in well-drained
fertile soil in either full sun or partial shade. The plant is
a slow grower.
Some of the possible insect problems are lacebugs, mites and scale.
Fireblight can be a disease problem. If you have a deer problem,
though, this plant is a good one to consider as it is not a deer
A variety to look for is 'Variegatus', named for its variegated
leaves edged in white which turn to rose red in the fall. Other
varieties include 'Ascendens', 'Dart's Splendid', 'Robustus' and
The multiseason landscape value of the cotoneaster sets it apart
from many other plant choices. Visit the JC Raulston Arboretum
for a look at the rockspray cotoneaster as well as other species
worth discovering. Learn more at http://www.ncsu.edu/jcraulstonarboretum.
