Snowball Viburnum

12 Jul

Viburnum Snowball (Viburnum opulus ‘Roseum’) deciduous, moderate growth to 10-15 feet in height with an equal spread, rounded growth habit, clusters of large, white flowers in spring, maple leaf-shaped foliage turns red in the fall, sun to light shade, deer resistant.

Viburnum is a large, diverse group of plants with generally oval, often handsome leaves and clusters of typically white, sometimes fragrant flowers. Blossoms are usually followed by single-seeded, often brilliantly colored fruit much appreciated by birds. Many viburnums are grown for their flower display, a few for their showy fruit. Many evergreen types are valuable as foliage plants. Here are some that do well in the Bay Area.

Viburnum davidii

Compact mound to 3–4 ft. high and wide. Handsome, glossy dark green, deeply veined leaves to 6 in. long. White flowers in 3-in. clusters open from dull pinkish red buds in spring; they are not showy but are followed by an arresting show of metallic turquoise blue fruit. Grow with acid-loving plants.

Viburnum plicatum tomentosum

A truly beautiful viburnum. Resembles the species but has lacecap flower heads: flat, 2–4-in. clusters of small fertile flowers edged with 1– 1/2 -in. sterile ones. Fruit is red aging to black; showy but not always profuse.

Viburnum tinus

Blooms from fall to spring; tight clusters of pink buds open to lightly fragrant white flowers. Bright metallic blue fruits last through summer. Dense foliage right to ground makes it good for screens, hedges, clipped topiary shapes. Can be trained as a small tree. Susceptible to mites; prone to mildew near ocean.

Viburnum trilobum

To 15 ft. tall, 12 ft. wide. Leaves look much like those of V. opulus; they emerge reddish tinged, mature to dark green, turn yellow to red-purple in fall. Lace­cap flowers appear in midspring.
