Comprehensive DescriptionRead full entry
Winged sumac is a native, deciduous, large shrub that rarely exceeds 10 feet. It has alternate, compound leaves, 16-24 inches long, with a winged leafstalk. The leaflets are narrowed or rounded at the base and sharply pointed at the tip with finely serrated margins. The leaflets are dark green and smooth above, and pale beneath, except along the midrib. Compact clusters of greenish-yellow flowers bloom from July to September. Fruits mature later in the fall. The fruiting head is a compact cluster of round, red, hairy fruits called drupes. Each drupe measures ¼ inch in diameter and contains one seed. Each cluster of drupes may contain 100 to 700 seeds. Fruit is produced on plants 3 to 4 years old. Because most populations of sumac have male and female flowers on separate plants, only the female plants produce seed. Occasionally, plants are found which have both male and female flowers. The germination of sumac seeds is enhanced by their passage through the digestive system of rabbits, ring-necked pheasants, and quail. The presence of fire also encourages increased germination. There are about 60,000 seeds per pound.
