Blue False Indigo (Baptisia Australis)
Blue False Indigo
While baptisias are amazing perennials, they have a good and bad side to them. The good side is that they can last up to 20-30+ years in the right conditions! But, something that can truly bother you as a grower is that they have very deep roots that can’t be transplanted once they’re established.
Perennial in zones 3-9. They’ll handle tough winters just fine, but in really hot zones (9 to 10) give them well-drained soil and go easy on the summer water.
They’re also in my roundup of plants that don’t respond well to division, definitely a “plant it and forget it” type
