How to Grow Sumac in Your Garden

Article: Don't Overlook Sumac For The Garden

Sumacs are fast growing, tough, and versatile. They are often ignored in the home landscape, partially because many people assume they are poisonous, and partially because they are so common in the wild that they are simply overlooked.

Sumacs spread by way of underground rhizomes and can take over small areas rapidly. They are not usually a good choice for people with small gardens, but if you have the space, there are plenty of advantages to growing them.

Friend or Foe?

Sumacs grow as open, spreading shrubs or small trees. They prefer full sun, and although they are often seen growing on slopes and in light, sandy soil, they are very adaptable to all types of light and soil conditions. It's for this reason that native varieties can be found growing in large colonies in nearly every part of the United States from Maine to Washington, and as far south as Texas.

New plants are produced and spread rapidly via underground rhizomes. Their ability to colonize quickly has made them useful for soil erosion projects in some areas, and gotten them listed as invasive species in others.

Using Sumac In Your Garden

Year Round Interest: Sumac is a good choice for landscape plantings around the home, providing that you have ample space and that you're willing (and able) to keep spreading colonies in check.

Every autumn, without fail and regardless of weather conditions, the sumac's green, fern-like leaves turn attractive shades of yellow, orange, and red. Few trees and shrubs exists that can equal their stunning show of color. In the winter, sumac's scarlet, velvety clusters of fruit, and smooth, crooked branches draw in neighboring birds and bring visual appeal to an otherwise stark landscape.

Landscaping: Use it to prevent soil erosion along slopes, streams and near ponds. It can also be grown as a windbreak, to create shade, or to cover bare areas where no other plants will seem to grown. Since the plants are resistant to salt, they are good solutions along shorelines and roads.

Wildlife: In the winter, sumacs will be appreciated by the birds. The berries are a preferred food source for ruffed grouse, ring-necked pheasant, eastern phoebe, common crow, northern mockingbird, gray catbird, American robin, wood thrush, hermit thrush, eastern bluebird and European starling. Although not preferred, since the fruit clusters hang from the branches all winter, it is also used as a "last resort" food by over 30 other species when little else is available. The green flowers in spring may seem insignificant to us, but are attractive to Honeybees.

Popular Ornamental Varieties

The most common variety grown in the home landscape is the Staghorn (Velvet) Sumac (Rhus typhina), which flourishes in Zones 4 to 8. It grows to a height of about 15 to 25 feet tall with a spread of 15 to 25 feet, and has a short, crooked trunk and irregular branches. Like most other sumac varieties, Staghorn Sumac has beautiful scarlet, fern-like foliage in the autumn and features velvety red, cone-shaped clusters of fruit on its branches in the winter.

Other popular ornamental varieties include:Shining Sumac (Rhus colallina), Smooth Sumac (Rhus glabra), and Fragrant Sumac (Rhus aromatica).

Where to get Sumac

Sumac can be obtained from native plant nurseries or specimens can be collected (with permission) from the wild. Most people who grow them in the home landscape are more than happy to share young plants. Dig up small shoots early in the spring before they leaf out.

Young plants can be raised in a nursery bed for the first year or two before moving them to their permanent home. Cuttings can also be made in the late fall, from roots or stems. Although possible, it's very difficult to grow sumac from seed. The seed coat is very hard and even in the wild, can take years to break down.

Identifying Poisonous Sumac

Many people are under the impression that all sumac varieties are poisonous. It's simply not true. Poisonous varieties of sumac are rare - in fact they are the exception, not the rule. Unlike their non-poisonous relatives, poisonous sumacs prefer wet conditions.

You'll find them growing near swamps, bogs, and other low-lying areas, exactly the opposite of where you would expect to find non-poisonous species growing (slopes and dry, sandy soil).

It's easiest to identify them in the fall, when their berries reach maturity. Unlike the red, upright, fuzzy berry clusters of non-poisonous species, the berries of poisonous sumac are white, smooth, and hang in downward-facing clusters.
