Culture

Easily grown in average, medium moisture, well-drained soil in full sun to part shade. Prefers moist loams, but tolerates wide range of soils. Tolerates clay soils better than most viburnums. Established plants prefer consistent moisture but have some drought tolerance. Prune as needed immediately after flowering.

Noteworthy Characteristics

Viburnum is a genus of about 150 species of deciduous, evergreen and semi-evergreen shrubs and a few trees from chiefly North Temperate regions extending into Southeast Asia and South America. They are grown for their attractive flowers, colorful fruit and attractive foliage. Some species have edible fruit or fragrant flowers. They are very attractive, versatile garden plants.

Several hybrids available in commerce today are derived from crossing V. japonicum (evergreen Japanese viburnum to 6-8’ tall) and V. dilatatum (deciduous linden viburnum to 8-10’ tall). These hybrids are semi-evergreen and typically grow to 8’ tall and as wide and generally feature white spring flowers in cymes, red berries in fall and maroon to purple fall foliage color.

Genus name comes from the Latin name of a species plant.

‘Emerald Triumph’ is the result of a cross between V. ‘Allegheny’ and V. burejaeticum. This is a compact, rounded, deciduous shrub that typically matures to 6-8’ tall and as wide. Showy white flowers in flat clusters (cymes to 3” wide) bloom in late April-May. Flowers give way to fruits (drupes) that mature to bright red in late summer but turn black by autumn. Leathery, glossy dark green leaves turn bronze to dark red in fall.
