Viburnum plicatum f. tomentosum, commonly called doublefile viburnum, is a dense, multi-stemmed, deciduous shrub with distinctively tiered horizontal branching that typically matures over time in a broad-rounded form to 8-10’ tall with a slightly larger spread. It is native to forests and thickets in China and Japan. Flowers bloom in late April-May in flat-topped, lacecap-like clusters (each to 2-4” but less frequently to 6” wide) which extend along the branches and above the foliage in double rows, hence the common name of doublefile viburnum. Each cluster has an outer ring of large, showy, snow-white, sterile florets (each to 1-2” across) surrounding a central mass of tiny non-showy fertile florets which when fertilized give way to egg-shaped 1/3” long fruits (red maturing to black) and viable seed. Ovate, toothed, strongly-veined, dark green leaves (to 4" long) turn burgundy red to purplish red in fall. A large number of cultivars have been introduced into commerce.
From Latin, viburnum is the name of a species plant, plicatum means pleated or folded in reference to leaf veins, and tomentosum means woolly in reference to fine hairs on young stems and leaf undersides.
'Shasta' is a cultivar that typically matures to 4-6’ (sometimes to 10’) tall and spreads to 9-12’ wide. This is a large shrub that produces abundant flowers in spring on horizontal branches followed by abundant red maturing to black fruits. Large flower clusters (each to 6” wide) feature showy outer snow-white sterile flowers (each to 2” wide). Introduced in 1979 by the U.S. National Arboretum.
