Robinia 'Purple Robe'
Overview
Black locust (Robinia 'Purple Robe') is an attractive ornamental tree which produces purple-tinged, sweet smelling flowers. It grows quickly and is hardy, making it suitable for colder climates. It’s also resistant to drought and pests, and doesn’t need pruning - making it a low maintenance option for busy gardeners. It grows up to 12m tall with an equally impressive spread reaching 6m. The bright clusters of flowers attract beneficial insects and birds to your garden, and its deep taproot makes it tolerant of dry soil. This species is ideal for creating a colourful, fragrant focal point in any garden.
