Ornamental Features

It features showy racemes of rose flowers with lilac purple overtones and yellow centers rising above the foliage from mid summer to mid fall. It has dark green evergreen foliage. The spiny oval pinnately compound leaves turn an outstanding red in the fall, which persists throughout the winter.

Planting & Growing

Chinese Mahonia will grow to be about 5 feet tall at maturity, with a spread of 5 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front, and is suitable for planting under power lines. It grows at a slow rate, and under ideal conditions can be expected to live for approximately 30 years. While it is considered to be somewhat self-pollinating, it tends to set heavier quantities of fruit with a different variety of the same species growing nearby.

This shrub does best in partial shade to shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type, but has a definite preference for acidic soils, and is subject to chlorosis (yellowing) of the foliage in alkaline soils. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This species is not originally from North America.
