Mahonia
Mahonia japonica
Family: Berberidaceae · Also called Oregon Grape, Japanese Mahonia, Beale's Barberry, Berberis tikushiensis, Aquifolium japonicum, Berberis japonica var. gracillima
Citrus & Bright · Winter bloomer
Mahonia is winter's most unexpected pleasure, drooping chains of soft yellow flowers cascading from the top of stiffly architectural, holly-like evergreen foliage from November onward. The contrast between the tough, spiny leaves and the delicate, fragrant flower sprays is mahonia's signature charm. Blue-black berries follow in spring.
protection, resilience, survival
In the Victorian language of flowers, mahonia means “Protection and resilience”. Named after Bernard McMahon, an Irish-American nurseryman who received plants from the Lewis and Clark expedition. Despite the Japanese species name, it was likely introduced to Japan from China centuries ago. The holly-like leaves and upright habit make it one of the most architectural winter-flowering shrubs, beloved by garden designers for structure.
Did You Know?
Mahonia berries are edible and quite tart, they make excellent jelly and were used by Native Americans (who had different species). The inner bark and roots are bright yellow due to berberine, used as a natural dye and traditional medicine. Despite looking like holly, mahonia is related to barberry. The pollination mechanism is triggered by touch, stamens snap inward when a bee lands.
Woodland understory and rocky slopes in temperate East Asian forests
Mahonia is native to Japan, Taiwan. It naturally grows in woodland understory and rocky slopes in temperate east asian forests.
