Iris bracteata
Iris bracteata
Siskiyou iris is a rare Pacific Northwest native that thrives in gritty, well-drained, slightly acidic soil under dappled light. It prefers dry summers and cool, moist winters, mimicking its natural habitat on rocky slopes in Oregon and California. Avoid heavy clay soils and overwatering, which can quickly cause rhizome rot.
