Hesperaloe parviflora is a close relative of Yucca with long, arching, narrow, succulent foliage that forms an open clump. In summer, red yucca produces tall wands of waxy, coral red flowers with yellow throats that are popular with hummingbirds. 'Coral Glow' has glowing coral pink to coral red flowers. To encourage bloom, plant in the hottest, sunniest spots.
