(Iris spp.)

Irises are an elegant perennial that naturally grow in the moist ranges of California. Its  showy flowers emerge in the spring to add delight and elegance to gardens. They tolerate  poor drainage and high moisture. If not planted next to a creek or in a naturally wet area,  it likes summer water every 2-4 weeks. It is more drought-tolerant near the coast where it  benefits from cooler temperatures and fog. Irises work great as an understory plant, along  borders and pathways, and with rocks to create a lush feel.
