Mahonia (Holly grapes) > Mahonia aquifolium, M. japonica and M. x media are evergreen shrubs with holly-like spiky foliage and sweet-smelling yellow flowers. They are often planted as low-maintenance shrubs. After the flowers appear dusky, dark purple small grape-like fruits. They are too tart to eat raw, but cooked with sugar make an intense sweet, sharp jelly. Mahonias prefer shady conditions but will tolerate sun if the soil is moist.
