Guelder Rose Viburnums

What is a guelder rose? Guelder rose viburnums (Viburnum opulus) are deciduous shrubs or trees that grow between 13 and 25 feet (4-8 m.) in height and 8 to 12 feet (2-4 m.) in spread, making them well-suited for smaller areas of the landscape. In late spring to early summer, they produce branching clusters of flowers that are usually white but sometimes shades of pink. The flowers give way in autumn to round berries that are red, blue, or black. These berries are mildly toxic and can cause nausea if they are eaten. The leaves are frequently mistaken for maple leaves. They are bright green in the summer and turn to orange and red in the fall.
