Handsome, award-winning Mahonia japonica (Japanese Mahonia) is an erect medium-sized evergreen shrub with a striking foliage of large, leathery, dark green leaves, each composed of 7-15 spiky leaflets. Long terminal clusters of lemon-yellow flowers, which smell of lily-of-the-valley, open over an extended period in late fall. They attract pollinating insects before giving way to grape-like clusters of glossy, round, blue-black berries. The fruits attract birds and wildlife. The lustrous evergreen foliage may take on red or purple tints when the weather turns cold. This handsome shrub is a great feature in the garden all year long.
