Baptisia 'Purple Smoke' (Wild indigo)

Baptisia 'Purple Smoke'

Wild indigo

Discovered by Rob Gardener of the North Carolina Botanical Gardens and introduced by Niche Gardens of Chapel Hill, NC. Apparently a chance hybrid of B. australis and B. alba, this has the charcoal-gray stems of alba and the blue color from australe, although it is more purple than B. australe. It is a good and vigorous grower and destined to be very much treasured.

Wild indigo Interesting Notes

A Niche Gardens/NC Botanical Garden 1996 Introduction. Charcoal stems and gray-green foliage, typical of Baptisia alba, are topped with enchanting, lupine-like flowers that are smoky-violet with a purple eye. Numerous flowers first open low on the bloom spike and ascend, with the flower stalk topping out at 4'. Mature plants of 3-4 years can bear over 50 blooming stalks in springtime gardens. This exciting, naturally-occurring hybrid of B. alba and B. australis offers the best of both species, and was found, watched over and nurtured by Rob Gardner, former curator of the NC Botanical Garden. 'Purple Smoke' thrives in lean, well-drained soil in full sun. - Niche Gardens

The genus name comes from the Greek word "bapto" which means "to dye" because some of the darker flowered species were used as dyes.

Baptisia 'Purple Smoke' Growing and Maintenance Tips

Grow in full sun or part shade in average to dry soil. Baptisia has a very deep tap root, giving it the ability to survive long dry periods and making it a challenge to move once it is established. Move in the early spring if you must. Full sun is best for the best flowering and performance.
