Burning bush / winged euonymus
Euonymus alatus
Burning bush / winged euonymus (Euonymus alatus) is a shrub suited to the Colorado Front Range. It matures to about 5–10 ft tall and 5–10 ft wide, needs medium water, and prefers full sun to partial shade. Increasingly considered invasive in eastern US and several states have restricted sales. Not on CO's noxious list, but consider native alternatives (Cotinus, Cornus sericea, Rhus trilobata) for similar fall color. Note: fall color is often muted here due to dry late summers.
