Add some drama to your garden this month with Mahonia ×media 'Winter
Mahonia ×media 'Winter Sun' is often taken for granted and overlooked until the winter season arrives. One of December's many surprises, it lights up the garden with bright, fragrant, yellow flower spikes. In spring, expect an encore performance, as its clusters of small, blue berries attract birds to the garden. These berry clusters give rise to its common name, grapeholly.
Mahonia is a member of the barberry family, Berberidaceae. Mahonia ×media is a hybrid between two Asian species, Japanese mahonia (Mahonia japonica) and the Burmese grapeholly (Mahonia lomariifolia). The Slieve Donard Nursery in Northern Ireland selected the cultivar, 'Winter Sun'. The genus Mahonia, received its name from botanist Thomas Nuttall in 1818. He gave this name in honor of the nineteenth century American horticulturist, Bernard McMahon (1775-1816).
There are three groups of Mahonia ×media 'Winter Sun' plantings at the JC Raulston Arboretum, but my favorite is easily spotted as you enter the Winter Garden. Here, you will find three mature multi-stemmed specimens grouped together that were planted in 1995 (Bed E19a).
This medium size, evergreen shrub is slow growing, but ultimately can reach 8' to 15' tall and 8' to 10' wide. Evergreen leaves are pinnate, glossy, spiny, and thick and help to provide structure in the garden year-round. Plant Mahonia ×media 'Winter Sun' in your garden in a site with rich, well-drained soil, and partial shade, and you will enjoy it for many years to come.

"A Virtual Tour of the Oak Genus" presented by Guy Sternberg, Starhill Forest Arboretum, Petersburg, Illinois. There are perhaps 500 or more oak species on Earth – no one knows exactly. Many of them are found in remote, fascinating parts of the world, and many of these cannot be seen in cultivation outside their native habitats. Studying them must be done on their terms, in their homelands. Join International Oak Society past president Guy Sternberg for a travelogue of oak excursions to Central America, Mexico, eastern and western Europe, and eastern and western Asia.
