Nevin's barberry

Description

Mahonia nevinii is an erect shrub approaching a maximum height of 4 metres (13 ft). It has a dense foliage of dark green to bluish-green spiny-toothed, spear-shaped leaflets. It flowers in racemes of 3 to 5 bright yellow cup-shaped, layered blossoms. The fruit is a spherical reddish berry appearing in bunches, in the summer. Some botanists treat Mahonia as part of the genus Berberis.
