One of the old-fashioned "snowball bushes" that has been a garden favorite for centuries, this plant is best known for its large heads of sterile flowers that open green and mature to ivory white. These blooms may last for weeks, but they result in no fruit. It is a large-growing, rounded shrub that may reach 12 feet tall and wide. Leaves are bright green during the summer, and turn a purplish red in the fall
Grow in well drained soil, preferrably of a loamy nature, in full sun to partial shade. While adaptive to a variety of soil types, best growth occurs in fertile sandy-loam or clay-loam soils. Tolerant of alkaline soils. Occasional and selective pruning of oldest wood will keep the shrub compact, densely leafed, and tidy; shearing makes it very twiggy (see Guides). It may be attacked frequently by aphids that distort tender young growth; control with insecticidal soaps. Also listed as V.o. 'Sterile'.
