About
Mahonia nervosa, Oregon grape, is a compact, suckering, evergreen shrub to around 60 cm with leaves composed of dark-green, spiny-edged leaflets that may turn red in winter. Yellow flowers in dense clusters 15�20 cm long in late spring are followed by blue-black fruits. An excellent low-growing, ground-covering mahonia for a shaded border.
About the genus
