What if you could get the ability to tolerate freezing temperatures and blazing heat in a single plant? Add a few other characteristics, such as beautiful flowers, drought tolerance and low maintenance, and you've got red yucca. It has all these traits packaged into one beautiful succulent plant that has found a home throughout Southwestern landscapes. In spring coral-colored flowers are borne aloft on tall stalks atop succulent grass-like foliage. Even when red yucca is not in flower, the grass-like foliage adds great texture to the landscape.

Distinguishing traits. Despite its common name, red yucca is not a yucca at all. The leaves of this succulent mimic the appearance of an ornamental grass.
Coral flowers with a yellow center appear on tall stalks beginning in spring and lasting through early summer. In cooler climates flowering can extend throughout the entire summer.

Also available in a yellow-flowered variety, red yucca can handle areas with western exposures and reflected heat. Flowering is at its best when red yucca is planted in full sun.
When not in flower, red yucca adds a welcome spiky texture to the landscape. It does best in the well-drained, slightly alkaline soil prevalent throughout the Southwest.

How to use it. Red yucca looks great planted in groups of three or five. Plant it near boulders, where its spiky texture will contrast with their rounded shapes. Red yucca is also great to add alongside pools, due to its low litter. It also makes a good container plant and is the perfect solution for a hot corner that receives reflected heat.
Show off the coral flowers by pairing red yucca with yellow-flowering plants, such as angelita daisy,

Baileya multiradiata),
damianita and
feathery cassia (
Senna artemisioides)

Planting notes. Plant it in full sun or filtered shade in well-drained soil. Water twice a month spring through fall. Red yucca needs very little water during winter — water once a month then in the absence of rain.
This is a truly low-maintenance plant. Prune the flowering stalks back to the base of the plant once they have dried. Divide large clumps of red yucca in spring every three to four years. Red yucca requires no fertilizer.
