Baptisia ‘Purple Smoke’

5 Photos


Baptisia ‘Purple Smoke’ is one of the oldest hybrid cultivars of false indigo, and it still remains one of the best for the home garden. Its charcoal-gray stems are beautiful when emerging from the soil and the gray color persists through flowering, creating a fine complement to the pale lavender flowers. A unique feature of ‘Purple Smoke’ is its miniaturized leaves that give the foliage a fine textured look. These small leaves are inherited from one of its parents, the dwarf-sized Baptisia australis var. aberrans. However, the habit of ‘Purple Smoke’ is slightly larger, yet still compact, at 36”h x 48”w.
