Baptisia has attractive green foliage and spikes of bright blue flowers in early summer make this native Texas plant a worthy addition to any garden.
Baptisia prefers full sun but tolerates partial shade, though too much shade causes lank growth that flops over easily. The soil should be of poor to average fertility, loose and well drained.
Once established, this tough perennial is unfazed by drought and heat. It resents disturbance, so it doesn’t need dividing.
Baptisia can be used in an informal border or a cottage garden. It is an attractive addition for a naturalized planting, on a slope or in any sunny, well-drained spot in the garden.
