doublefile viburnum
(Viburnum plicatum tomentosum)
This species is Introduced in the United States
ORIGIN: China, Japan, Korea, Taiwan
GROWTH TRAITS: There are multiple forms and varieties of Viburnum plicatum. This description and the corresponding images and distribution map pertain to one form with fertile florets, frequently referred to as V. plicatum var. tomentosum or doublefile viburnum. This plant typically grows as a multi-stemmed shrub 8-10' (2.4-3 m) tall and is wider than tall, though some individuals may grow to 15' (4.6 m) in height. Branches extend horizontally, giving the plant a layered appearance. Young stems may be covered in soft hairs. The bark is mostly smooth and gray-brown with distinct orange lenticels. Leaves are elliptical to ovate, 2-4" (5-10 cm) long, and hairy on the undersides and the petiole. They are green in summer, turning burgundy in the fall. Flowers appear in flattened clusters in 'doublefile form' along branches. Each cluster contains an outer ring of large, showy, sterile florets surrounding a mass of tiny, non-showy fertile florets. Fruits are oval-shaped, 0.5" (13 mm) long, and green initially but turn red and then black at maturity.
REPRODUCTION: Species spread by seed but can also re-sprout from the root system following damage. Seeds of many viburnums remain viable for up to 10 years.
HABITAT: Tolerates a wide range of soil conditions and can grow in full sun to partial shade. Grow best in mesic soil in full to partial sun and are typically found at forest edges, fields, and disturbed forests.
LOOK-ALIKES: Several additional viburnum species are native to or have been introduced to North America, and many are difficult to differentiate. They vary slightly in leaf shape, fruit color, buds, and flower and fruit structure.
