Purple Robe Locust Tree (Robinia pseudoacacia 'Purple Robe') is an improvement of the native Black Locust tree.
It's become incredibly popular because of the great purple flower color and excellent fragrance. But once established, tough Purple Robe Locust trees are also super hardy and drought tolerant with a brisk growth rate of 2 or 3 feet of growth each year.
Purple Robe Locust trees develop incredible, long clusters of purple colored flowers in mid- to late spring that look very much like Wisteria flowers. These beautifully fragrant clusters cover the tree profusely and may be up to eight inches long each!
It is an impressive display, and you will definitely want to cut a few and bring them indoors to enjoy in a cut flower arrangement.

Easy Care Native Tree
Have you ever noticed a group of white-flowering trees blooming in mid-spring along pasturelands and fence lines? They are growing beautifully without any care in poor soils, with open exposure, and where little additional water would ever get to them?
This is likely a native tree called a Black Locust (Robinia pseudoacacia) and they have been widely planted into the East Coast, Midwest and into the Southern parts of the country. The native species blooms in mid-late spring and the flowers are white and fragrant.
The variety 'Purple Robe' features beautiful, fragrant purple flowers. Bees and beneficial insects love the flowers.
Each spring, the leaves emerge reddish bronze, before maturing to dark blue-green. The large compound leaves have smaller blue-green leaflets, and you'll love the fine-textured look of the tree in summer.
Fall clean up is easy with these small leaves, too!
