Rocky mountain sumac is a native shrub with graceful, dark green compound leaves. The leaves turn a brilliant red in the fall.
It produces pyramid-like flower clusters of creamy yellow flowers in July, which later turn into velvety dark red fruit.
It suckers to form colonies, which makes it a good choice for mass plantings. This variety is about half the height of smooth sumac.
Rocky Mountain sumac is not currently growing at the Xeriscape Demonstration Garden. It grows well in the Colorado Springs area, but may be susceptible to deer damage.
Pull up sucker plants to control colonization and prune any dead or damaged branches.
