Description

edit

Berberis pinnata is a dark green bush which resembles holly with its serrated leaves. It has one to two inch long clusters of small yellow flowers.[3] The fruit is a purple berry with many seeds 6–7 millimeters in size.[4]

Taxonomy

edit

Berberis pinnata was given its first scientific description and named by Mariano Lagasca in 1816. As part of the botanical debate over the correct classification of species it was placed in Mahonia by Friedrich Karl Georg Fedde as Mahonia pinnata in 1901. Though scientific disagreement continues, as of 2023 the majority of botanical sources list this species in Berberis.[1][5][4]

Names

edit

Mahonia is named for Bernard McMahon (1775-1816), an American horticulturist.[6] Pinnata means 'set in two opposite rows' or 'pinnate', and is a reference in this case to the arrangement of the leaflets.[6]

Uses

edit

The Berberis pinnata fruits have also been used to produce purple dye. The shrub is used in landscaping as an ornamental plant. Songbirds eat the berries.[3]

Conservation

edit

One subspecies of this plant is very rare and is federally listed as an endangered species. It is known only from Santa Cruz Island, one of the Channel Islands of California, where it is known from 13 or fewer individuals.[7]
