Baptisia australis

Blue False Indigo

Baptisia australis, or Blue False Indigo, is an upright perennial which features violet blue, lupine-like flowers in erect spikes extending well above a foliage mound of clover-like, bluish-green leaves. The flowers are like manna to bees, particularly queen bumblebees. Hummingbirds have been known to occasionally visit the blooms of baptisia. 

Flowers give way to seed pods which turn charcoal black when ripe and have considerable ornamental interest. Seeds rattle around in the blackened pods which were once popularly used by children as rattles. Stems with seed pods are a pretty addition to dried flower arrangements.  As plants age, they develop more stems and become broader and bushier.

Especially attractive to Orange Sulphur, Clouded Sulphur, and Eastern Tailed-Blue butterflies.

Baptisia is a host plant for larvae of the Wild Indigo Duskywing butterfly, Silver-Spotted Skippers, Dog Face  Sulphur, Orange Sulphur, Clouded Sulphur, Eastern Tailed-Blue, and Hoary Edge Butterflies! Bumblebees love it too!

Blue False Indigo Growing and Maintenance Tips:

Easily grown in average, dry to medium, well-drained soil in full sun to part shade. Best in full sun. Tolerates drought and poor soils. Over time, plants develop slowly expanding clumps with deep and extensive root systems, and should not be disturbed once established.

May be grown from seed, but takes several years to establish. Trimming foliage after bloom helps maintain rounded plant appearance, but eliminates the developing seed pods which are so attractive.
