Frangula alnus 'Ron Williams'
Alder buckthorn (Frangula alnus 'Ron Williams') is an amazing plant species. This tough evergreen shrub is low maintenance and easy to care for. Its glossy green foliage provides year-round interest, and its berries can be used in jams and jellies, making it an ideal edible landscaping choice. Its dark green leaves turn red in the fall, providing an extra pop of autumn color. It grows quickly, making it great for areas that need quick screening or cover. Plus, its purple-black fruits attract birds and other wildlife. Alder buckthorn is a great way to add color and diversity to your garden!
