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.
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.
Problems
Potential disease problems include bacterial leaf spot, mildews and crown gall. Potential insect problems include aphids and scale. Deer tend to avoid this plant.
Uses
Shrub for mixed borders or foundation plantings. Specimen. Screen or hedge.
