When to plant Blue False Indigo
This clump-forming perennial blooms best in full sun in average, well-drained soil, and is propagated by seed or stem cuttings. Its deep taproot makes it drought tolerant but difficult to transplant once established, so site it where it can stay; space plants 24 to 48 inches apart.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
