Though they are not related, mahonias and hollies have superficial similarities in terms of their shiny, often prickly foliage.
MAHONIAS, commonly called the Oregon Grape, are hardy shrubs, shade and lime tolerant, winter flowering, fragrant, evergreen and loved by flower arrangers.
Cut back woody stems of mahonias after flowering to encourage new growth.
MAHONIAS can be a trifle spiky with their holly-like leaves, but when they are in flower their brightest yellow flower spikes are really eye-catching.
Mahonias also have the advantage of tolerating shady conditions, thus even the most dismal corner of the garden can be livened up.
All mahonias are evergreen, and can be good architectural plants, giving good shape/foliage in a garden or border.
So mahonias are especially lovely and are well worth growing.
Mahonias like fertile soil with added organic matter and do best in full or partial shade, where the soil is moist all the time.
