Lewis' mock orange is named for the scientist and explorer Meriwether Lewis who first collected specimens. It is also known as Indian arrowwood for its utility to the tribes of the western parts of North America where the plant originates. Lewis' mockorange is the native flower of Idaho.

It grows in a rounded form to about ten feet in height and width with medium green leaves. In late spring it bears masses of large orange-scented white flowers up to three inches in diameter which are frequented by bees and other pollinators. Lewis' mock orange prefers very sunny conditions and requires well-drained soils, and can tolerate drought. Plant where it can spread and the older canes can arch gracefully.
