Kalkora Mimosa

Albizia kalkora (al-BIZ-ee-a Kal Kora)

Family: Fabaceae Non-native Understory (15-40 ft)

The Kalkora mimosa is a member of the legume family (Fabaceae) native of Northeastern India. Kalkora Mimosa is limited in cultivation in the United States with a naturalized population in Durham, North Carolina. It can form into medium to large trees and may be found in thickets or thinly planted forests at sea level to 6500 feet. The crown is graceful and spreading to provide shade. The plant can grow as a shrub or tree generally 8 to 25 feet tall but up to 60 feet tall in its native environment. Plant in average well-drained soiled in full sun to partial shade. If pruning is needed do so in late winter. The white to yellowish powder-puff blooms that occur in May and June are followed by flattened legumes containing 4-12 seeds. The leaves are compound and green and fold closed in the evening until morning. The tree is similar to the silk tree or mimosa which has an abundance of pink flowers. The two trees have been noted to hybridize together. They both readily self-seed and have the potential to be invasive. Please consider planting native trees. See suggestions to the left. Insects, Diseases and Other Plant Problems: No significant problems.
