Snowball bush viburnum is a popular and easy-to-grow hybrid shrub with a dense, rounded growth habit. It is highly prized for its large, white spring flowers. The flowers begin apple-green in color, morph into white, and eventually fade to rose color, looking much like hydrangea blossoms. Best planted in the spring or fall, this fast-growing shrub has dark emerald-green leaves similar to those of maple trees, and the 3-inch clusters of spring flowers are followed by small red berries that eventually ripen to black. At maturity, the snowball bush reaches 6–12 ft. tall, 6–10 ft. wide. The best location for a snowball bush viburnum is usually in full sun.
