General Culture:
Easily grown in average, medium, well-drained soil in full sun to part shade. Prefers moist, rich soils with good drainage.
Noteworthy Characteristics:
'Shasta' is a broad, dense, horizontally-branched, multi-stemmed deciduous shrub which typically matures to 6' tall and 12' wide, and is distinguished from V. p. forma tomentosum by its greater horizontally-spreading habit and its larger flower clusters and sterile flowers. Non-fragrant white flowers in flat-topped clusters (4-6" diameter umbels) bloom in profusion along the branches in mid to late spring. Flower clusters appear in two rows or files, hence the common name of doublefile viburnum. Flower clusters have a lace-cap effect (small, non-showy inner fertile flowers with a showy outer ring of pure white sterile flowers). Fertile flowers give way in July to large clusters of red berry-like drupes which eventually mature to black. Fruits are attractive to birds and wildlife. Ovate, dark green leaves (to 5" long) turn an attractive reddish purple in fall. Introduced in 1979 by the U.S. National Arboretum.
Problems:
No serious insect or disease problems.
Uses:
Specimen or group. Shrub border, foundation planting or hedge.
