Extra notes and interesting information:
Introduced to cultivation in 1822 and now still
coveted in Europe. One of our best and most useful
native ground covers. The fruits are loved by birds
and animals. Native peoples ate the berries raw, mix
them with sweeter berries and made them into dry
cakes. Bark is bright yellow inside and was used for
make a yellow dye for baskets and other materials.
Many botanists now regard Mahonia to be members of
the genus Berberis; still usually regarded as
Mahonia in the nursery trade.
