Vancouveria hexandra, the white inside-out flower, is a perennial herb in the barberry family Berberidaceae. It is found in southwestern British Columbia, western Washington and Oregon and northwestern California and is a common understory herb in dry to moderately moist woodlands. Inside-out flower is a perennial wildflower that spreads and creeps slowly by rhizome.
This plant grows 8–16 inches high with compound leaves in triplets and is usually found in dense patches. It gets its name from the small delicate white flowers with petal-like sepals that are swept back abruptly as if in the process of turning inside out. It is reliably low-maintenance, even by native plant standards. Attractive to bees and other pollinating insects. Zone 5-7.
Other Names: American barrenwort, rareseeds, rare wildflower
