Viburnums for Every Garden

The range of aesthetic characteristics that viburnums display is a gardener’s delight. You can choose plants that are evergreen, semi-evergreen or deciduous. Some species are under two feet in stature while others are towering 20 footers. Viburnum leaves can be rounded or lance-shape, smooth, velvety or rough, and often deeply veined to give the leaf an undulating appearance. The often fragrant flowers are white or pink, and most species bloom between early spring and early summer. The fruit (drupes) set in the late summer are metallic blue, bright red and in some species change from red to deep purple as autumn progresses. The fall color on the deciduous types is equally striking ranging from bright clear yellow, to brilliant crimson, to a deep rusty maroon. Read more about Viburnums for Every Garden
