Description

The Red yucca has become one of the most popular flowering accent plants in warm and dry climate regions such as the Inland Empire. It is an evergreen, strap-leaf perennial with stiff arching foliage and dramatic ascending spikes of colorful flowers in spring. It is a clumping plant that grows and divides into numerous plants, reaching 2-3 ft. tall and 3-4 ft. wide. Tubular flowers are commonly coral-red with yellow throats, however many new colors are now available from nurseries.

The Red yucca and its several cultivars are easy to grow throughout the Inland Empire. They are well adapted to sun, heat, cold and summer drought, and grow on many types of soils. They are good plants for containers, on slopes, around boulders and as feature plants in Mediterranean and southwestern style gardens. They have low maintenance needs and periodic deep watering in summer. Cultivars include: H. p. 'Yellow' with yellow flowers, H. p. 'Brakelights' with candy-apple red flowers, and H. p. 'Desert Flamenco' with coral-pink flowers.

Water Needs

Red yuccas are well adapted to sunny microclimate locations in the Inland Empire where they thrive in heat and with normal winter rainfall and low amounts of summer water. They are colorful flowering accent plants for courtyard and southwestern plantings in both commercial and residential settings. Monthly deep watering from spring through fall will enhance its spring flowering cycle and help maintain good foliage character. It should be noted there are several winter months marked by an asterisk (*) when rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water depending upon exposure conditions and size.
