It has been said that a garden without a Viburnum is akin to life without music and art. 'Shasta' is the first double-file viburnum cultivar to result from a breeding program for viburnum improvement. The abundant, large, lace-cap inflorescence have sterile marginal florets that are 1 1/2 times larger than those found on other cultivars, and often have 5-15 inner sterile florets dispersed among the center fertile flowers. The growth habit is strongly horizontal, twice as wide as high. Dark green leaves with 8-12 pairs of nearly straight veins. Bright red, upright fruit clusters ornamental for several weeks in late July. Fall coloration is dull purplish-red to maroon.
