Japanese Mahonia

Japanese Mahonia (Mahonia japonica)

Japanese Mahonia (Mahonia japonica) is a distinctive evergreen shrub prized for its bold, holly-like foliage, cascading clusters of fragrant yellow winter flowers, and graceful, spreading form. Native to East Asia, this shade-tolerant species offers outstanding seasonal interest and architectural texture, especially in woodland gardens and shaded borders. Its early blooms and bird-attracting berries make it both ornamental and ecologically beneficial.

Distinctive Features

This mahonia features long, pinnate leaves composed of sharply toothed, leathery leaflets that emerge bronze and mature to a deep green. In late winter to early spring, it produces arching racemes of lemon-yellow flowers with a sweet, lily-of-the-valley fragrance. These are followed by clusters of blue-black berries that add seasonal contrast. Japanese Mahonia typically grows 4 to 6 feet tall and wide, developing a layered, slightly arching habit as it matures.
