Baptisia forms tall, gorgeous spikes of pea-like flowers over blue-green foliage in mid-spring. Also known as False Indigo, Baptisia prefers average to dry soil and can even tolerate clay. Its taproot makes it particularly drought tolerant, but also makes established plants difficult to move. This tough perennial is usually pest and disease free – a favorite among gardeners. False Indigo is a North American native typically hardy to zones 4-9. Attractive to butterflies and deer resistant.
