Mahonia aquifolium is a species of flowering plant in the family Berberidaceae and it grows to 1–2 m (3 ft 3 in–6 ft 7 in) tall by 1.5 m (5 ft) wide, with pinnate leaves up to 30 cm (12 in) long, each leaf made up of spiny leaflets. The leathery leaves resemble holly and the stems and twigs have a thickened, corky appearance. The flowers, borne in dense clusters in late spring, are yellow, and are followed by spherical dark dusty blue berries.

Oregon grape root: Cultivation & Harvesting
considerations for growing and harvesting oregon grape root

Mahonia aquifolium often occur in the shady understory of Douglas-fir forests (although other forest types contain the species) and in brush lands in the Cascades, Rockies, and northern Sierras.

This plant tolerates poor soils and can adapt to a wide range of soil conditions.

Sow the ripe seed in the spring in a cold frame. Plant the seedlings into pots for their first winter, plant into the garden the next spring or summer.

The roots are harvested in late autumn or early spring and dried for later use as either cut pieces or powder.

Store dried root pieces or powder in an airtight container in a cool, dry place.
