Rhus lanceolata: Texan Sumac¹

Edward F. Gilman and Dennis G. Watson²

Introduction

Texan Sumac forms a loose, spreading small tree, reaching up to 25 feet in height. Most specimens only grow to about 12 to 18 feet tall. The shiny, pinnately compound leaves change to a brilliant orange, red, or yellow in the fall before dropping. The yellowish-white, summertime flowers appear in 6 to 10-inch-long and wide, terminal panicles and are quite showy. The hairy fruits which follow are orange/red and mature in October.

Use and Management

Training is required to make this large shrub into a tree. Begin by staking the main stem in the upright position for a year or two and develop branches beginning at two to four feet from the ground. Space branches 8 to 12 inches apart and be sure than they form a wide angle with the trunk. This will help ensure that they are well attached to the tree. Occasional pinching or heading back of the terminal shoot and branches will increase branching. Suckers from the base of the trunk may have to be removed periodically to maintain a neat appearance.

Place Texan Sumac in a prominent location in the landscape in the full sun. It is a nice tree for planting in a low ground cover to display the interesting trunk and branch arrangement. The fine-textured foliage, showy flower display and bright fall color combine to make this small tree suitable for increased usage in southern landscapes.

Sumac should be grown in full sun on well-drained soil, acid or alkaline. This tree is often found on limestone or clay soils with a high soil pH in its native habitat, but it also grows on acidic soil. It would be well suited for inclusion in a low maintenance landscape where plants receive little if any irrigation. Too much irrigation and fertilization can lead to plant decline.

Propagation is by seed.

Pests and Diseases

There are no serious pests or diseases as long as plants are not overwatered.
