Frequently Asked Questions about the Blue False Indigo
Is blue false indigo toxic?
Yes, blue false indigo (Baptisia australis) is considered toxic if ingested in large quantities. It contains alkaloids that can cause nausea, vomiting, and other symptoms in both humans and animals — but it is not typically dangerous with brief skin contact.
How fast does blue false indigo grow?
Blue false indigo grows slowly, especially in the first few years while it establishes its deep root system. Once mature (usually by year 3–5), it becomes a large, long-lived clump that rarely needs attention and can live for decades.
When does blue false indigo bloom?
Blue false indigo typically blooms in late spring, from May through June, producing tall spikes of violet-blue flowers. The dramatic inflated black seed pods that follow provide ornamental interest through fall and winter.
Does blue false indigo spread?
Blue false indigo spreads slowly by rhizomes and forms widening clumps over time. It may also self-seed, but it is not considered aggressively invasive. Removing seed pods after flowering will limit self-seeding.
Is blue false indigo a native plant?
Yes, Baptisia australis is native to much of the central and eastern United States. It is widely praised as an excellent low-maintenance, pollinator-friendly choice for native plant and prairie gardens.
