Cercis canadensis var. alba
White Flowered Redbud
Native to (or naturalized in) Oregon:
- Deciduous tree. Small white flowers appear before the leaves.
- Sun to part shade
- Hardy to USDA Zone (3) 4 Discovered in a nursery in Carthage, Missouri in about 1903, but may have been discovered in Australia as early as 1792. It or something similar is sold as the cultivar ‘Alba’. There is also another white flowering form know as ‘Royal’ or ‘Royal White’, this selection originated in Illinois from a seedling tree. It is more compact, flowers earlier and more abundantly, and has larger flowers than ‘Alba’ (Jacobson, 1996, also see Dirr, 1998).
