We believe Shasta to be the finest of all Doublefile Viburnums. Bred at the U.S. National Arboretum, it was released to the trade in 1979. This is not a small shrub. It does grow to only about 6 ft. in height but its habit is strongly horizontal and it can reach up to 12 ft. in width. Its certainly a big shrub, but its show of flower, fruit and fall color is oversized as well.

Shasta has possibly the finest floral display of the Viburnums. The lacecap type inflorescences are large (up to 6" across) and abundant. They're 50% larger than other varieties of Doublefile. They're arranged in two rows (or ranks) along the horizontally held branches, hence the common name, Doublefile. The pure-white flowers literally smother the branches and are effective in late spring for many weeks. Bright red berry-like drupes follow in July and are quite attractive until used as a smorgasbord by Robins and Waxwings. Fall color is outstanding.

Ornamental Characteristics: Heavy bloomer with 4 to 6" pure-white flower clusters (cymes) arranged in two rows along the horizontal branches. Blooms in late spring. Red berry-like drupes ripen in July and, if not eaten by birds, slowly darken to black. Fruit display very effective. The dark green foliage turns an attractive reddish-purple in autumn.
