For Your Garden - January 2022
Native plants provide beauty as well as food and shelter for wildlife. Native species are adapted to the Illinois climate. They require little or no watering and are resistant to drought, insects and most diseases. Because they are perennials, you can welcome their presence year after year.
smooth sumac (Rhus glabra)
Smooth sumac is a small, deciduous tree or shrub. Its twigs are red-brown or green-brown and covered with a white coating. Its compound leaves may have as many as 31 leaflets. Male (staminate) and female (pistillate) flowers are generally on separate plants. The small, green-white flower clusters develop in June and July. The fruit is a small, red drupe (a seed enclosed in a hard, dry material that in turn is covered with a fleshy material). Drupes are covered with tiny hairs. Smooth sumac grows throughout Illinois in prairies, roadsides, fields and woods. Its leaves and fruits turn bright red in fall. The flowers are a good source of pollen and nectar for many pollinating insects, and the fruits help sustain many songbirds and game birds in the winter.
