Physical description: Japanese pachysandra is an evergreen plant that
forms a dense and solid carpet. It has alternating leaves that
are dark green, glossy, and lightly toothed. The leaves are ovate,
2 to 4 inches long, and 0.5 to 1.5 inches wide. The stems are
slender, upright, and greenish, while the flowers are white,
and in terminal spikes. The flowers are neither numerous nor
particularly showy.
Optimal growing conditions: Partial to full shade is preferred; the leaves
will yellow if exposed to full sun. Japanese pachysandra grows
best in moist, well-drained soils with a pH of about 5.5 to 6.5,
with good organic matter content. Poorly drained, heavy clay
soil should be avoided.
Susceptibility to pests and diseases: Volutella pachysandrae, or leaf blight,
can become serious. Root rot and Euonymus scale can also cause
significant damage.
Use:
This plant is good in masses under the dense shade of trees on
slopes or level ground. It is also good for erosion control.
Additional Notes:
It can be difficult to replant vegetation in an area which has
contained an established bed of pachysandra. Pachysandra is thought
to be allelopathic.
