African Sumac is a dense shade tree, rather graceful with its arching branches and weeping foliage. It is tough and reliable in dry conditions, though it looks best with regular deep watering. It is susceptible to Texas root rot. It is effective as a screen or windbreak, and as an evergreen specimen. It may require regularly scheduled light top-trimming (but not necessarily shearing) of vigorous top shoots to maintain its height below 25'.
Native to South Africa.
Trees may be referred to as male or female.
