This plant produces cream-colored flowers in April and May. The seedlings grow slowly and several years pass before the plants reach reproductive maturity.Baskin, C. C., et al. (1972). Observations on the ecology of Astragalus tennesseensis. American Midland Naturalist 88(1) 167-82. The species is adapted to drought, remaining metabolically active in habitat that is dry over the summer.Baskin, C. C. and J. M. Baskin. (1974). Responses of Astragalus tennesseensis to drought. Changes in free amino acids and amides during water stress and possible ecological significance. Oecologia 17(1) 11-16.
