Ah the Red Yucca, one of my favorite Central Texas Landscaping Plants. 

Texas Red Yucca Hesperaloe parviflora

Description:

Hesperaloe parviflora is native to Central and West Texas.  They grow much like an ornamental grass continuing to spread wider with age.  Red Yuccas emit long dark green spineless leaves from the center of the plant to form an array of evergreen foliage.  They bloom from spring to late fall, usually May through October.  Once in bloom the Red Yucca will sprout multiple 1/2″ to 1″ stems covered with light red bell shaped flowers.  Although the Red Yucca is not a true Yucca, it is a succulent.  Deer will eat the flowers but not the foliage and Humming Birds are attracted to them.  The combination of their drought tolerance, evergreen foliage and vibrant color make the Red Yucca a must have in Central Texas landscapes.

Maintenance/Care:  Require very little maintenance, occasional removal of dead stocks in the winter.

Height/Width:  Medium size shrub, grows up to 2′-5′ Tall and 4′ wide.

Water:  Very drought tolerant shrub. Can die from over watering, plant just a little bit higher then the surrounding elevation to help avoid this.

Light:  Full sun to maximize the number of blooms. Will bloom in part shade as well but tends to have more dead foilage when planted in areas with more shade.
