Baptisia australis 'Caspian Blue'
An upright plant that occurs in rich woods, thickets and stream banks from Pennsylvania to Tennessee.
Patience is required with this one as it takes time to establish. The thick roots are deep and extensive so it should be planted in a permanent position and left undisturbed.
You will eventually be will be rewarded with a large clump of magnificent, lupin-like flowers of the deepest purple through May and June.
The bluish-green, clover like foliage and black, rattling seed pods add to its appeal. It can take 2-3 years before it really gets going but is tolerant of poor soil, drought and is exceptionally long lived.
A firm favourite in our garden, beautiful and reliable.
