Viburnums offer something for everyone. There are more than 150 species and they run the table on shrub and tree characteristics. Depending on the variety, Viburnums can be used as hedge or screen plants, foundation shrubs or specimen plants. They may be deciduous, semi-evergreen or evergreen, can live in dry or wet soils, full sun, or deep shade. Most varieties flower, some are fragrant, and some produce berries for wildlife. Viburnums are native to many parts of the world, and in North America will grow in USDA hardiness zones 2-9 (but more commonly 4-8). And if you’re in love with a Viburnum you planted, they’re easy to propagate so you can have a second at no cost. There’s really nothing not to like about Viburnums.

Viburnums are one of the most versatile plants

Depending in the variety your Viburnum may:

Be a tree that grows to 30 feet or a shrub that hugs the ground at 1 foot.
Be evergreen, deciduous or semi-evergreen with leaves that may be large or small, and of various shapes.
Produce fragrant flowers in spring or fall.
Produce colorful berries prized by wildlife.
Be tolerant of wet soils or require dry soil only.
Prefer heavy shade or full sun.

Please read the plant tag to learn the specifics of your Viburnum.

Viburnums offer year-round interest

Beautiful, showy flowers

Most Viburnums flower creamy white or pale pink in mid-late spring, but a few flower in autumn. The blooms appear in various shapes: flat, vase, lacecap, snowball or dome-shaped. Many Viburnum flowers are fragrant, some remarkably so, and some have no scent at all.

Colorful berries

Most Viburnums produce berries that are prized by wildlife and persist until mid-fall or winter or until the birds snatch them. The berries may be red, pink, blue, black, yellow or orange.

Blazing fall foliage

Some Viburnums are deciduous, and others are evergreen or 3/4 evergreen (they only lose leaves for two months). Deciduous leaves turn blazing scarlet red, yellow, violet or purple in fall.

Are Viburnums native to North America?

Viburnums are native to many parts of the world, from Mexico to North America to China, Japan, India, and beyond. Please choose a variety native to your region for best success in your garden and to support local wildlife and pollinators. Check the plant tag or google the variety you’re considering.

Viburnums are easy to care for

Planting viburnums

When planting, test your soil to learn the pH. If it’s slightly acidic, between 5.5 and 6.5, your Viburnum should have no problems. Most prefer soil on the slightly acidic side, so aim for 5.5. If it’s alkaline – above 6.5 – acidify the soil with peat moss or elemental sulfur. But check the plant tag first or do some research on the variety you’re planting, because there are a few exceptions.

All viburnums require soil that drains well, as do most plants. If you have heavy clay, add organic matter like compost to loosen it up. Plant in the opposite season from flowering: if it’s a spring flowering variety, plant in the fall, and vice-versa. You can plant a spring-flowering variety in very early spring, but keep the plant well-watered through spring and summer to help it establish. I’ve successfully planted Viburnums as late as mid-June.

Follow basic planting rules:

Dig a hole as deep as the root ball and twice as wide.
Set the plant in the hole so that the top of the root ball is level with the soil.
Backfill the hole halfway with the soil you just removed. Do not add fertilizers or compost. Water in to settle the soil. Then fill the hole to the top, again with the same soil you dug out initially. Water again to settle the soil.
On the soil surface, form a rim of soil around the outer edge of the hole. This will help keep water around the root zone for the first season.
If planting more than 1 Viburnum, check the plant tag to learn the mature height and width and space appropriately.
Add 2 inches of compost on top of the soil around the root zone.
If mulching, use natural materials such as pine bark, pine straw, or cedar wood.

Fertilizing viburnums

As with most shrubs, add 2 inches of compost around the root zone once or twice a year, and it will have no need for fertilizer in most soils.

Pruning viburnums

Viburnums do not need regular pruning, except for dead wood or hazards, and in fact do best if you leave them alone. Height and spread can be regulated with selective pruning in early spring, but this will remove flower buds from the tips of branches. If the plant is growing beyond its space, prune appropriately to contain it, but don’t try to shape it with a hedge shear, or you’ll lose the flower buds. The optimum time to prune a Viburnum is just after it blooms.

Pests and diseases of Viburnums

Viburnums have very few problems with pests or disease. They may occasionally be bothered by aphids, powdery mildew, root weevils, spider mites, scale, thrips, or leaf spot, but none of these typically poses a serious threat to the plant.
