- Deciduous tree, 30-50 ft [9-15 m] tall, ascending, open. Described as thornless, but some plants offered as Purple Robe have typical R. pseudoacacia thorns. Leaves, 17-21 leaflets, bronze- red at first then bronze-green in summer. Flowers large, dark rose-pink, appear before those of the species.
- Sun. Drought tolerant.
- Hardy to USDA Zone 3 Apparently the result of an intentional cross by
William Silva between R. ambigua 'Decaisneana' and R. hispida 'Monument'.
