False Indigo (Baptisia)
Baptisia australis
Family Fabaceae
False indigo is the perennial you plant once and argue with never — a native that builds a shrub-sized mound of blue-green foliage, raises spires of true indigo in spring, then finishes with ornamental black seed pods that rattle into winter arrangements.
Its deep taproot makes it drought-proof and heat-proof where lupines melt, deer leave it alone, and bees crowd the bloom. It takes a few seasons to settle, then holds its ground for decades without help. Choose its spot with care — this one is staying.
