I don't know why False indigo, Blue Wild Indigo
Baptisia australis is not grown more frequently, it is a beautiful plant. It is one of those plants that even looks great when it is not in bloom, it is trouble free, lasts for years and years, it behaves itself, has lovely blue seed pods in the fall, what more could one ask for?? It is in full bloom right now in zone 4, Iowa.
We received almost 2 inches of rain last evening and last night. So no watering for a couple of days at least.
