Also known as ‘Oregon Grapes’ Mahonias are a fantastic winter flowering, cold tolerant evergreen shrub or tree.
A plant for year round interest in the garden, Mahonia have a number of garden worthy characteristics. Wonderful yellow flowers in late winter. Blue berries through summer and great foliage year round. They are also just about pest free and require little care once established.
So what are the drawbacks ?
Probably the only problem is that birds love the berries. In rural areas they can spread the seed and Mahonias can become a bit of a weed.
The foliage on most species resemble holly and the fruits look like grapes, however Mahonia are not related to either. And species come from both China and North America.
Taller growing Mahonia are an excellent choice for the rear of the border, while shorter and prostrate forms are useful in a range of landscape situations.
They are popular plants in the following states, Oregon, Washington, North Carolina, South Carolina, Georgia, Maryland and Tennessee
Mahonia prefer a humus rich but well drained soil, and all grow best in dappled or light shade. They can be fertilzed with same fertilizer used for Azaleas and Rhododendrons.
