Hesperaloe parviflora, also known as Red Yucca, is a moderately growing perennial often used in Texas native and water wise landscaping. It is hardy in all of Texas, the south and into the mid-west, from zone 5 to 11, and requires full sun. Red Yucca is an evergreen plant with long slender succulent like leaves and tall rose pink flowering stalks with small cup like flowers all along them. This plant can grow to be 3 to 4 feet tall and wide in the landscape with vertical or draping flower stalks up to 6 feet tall. It is a great residential design plant due to its relatively deer resistant nature, for example deer will most likely eat the red blooms but will spare the unpalatable evergreen foliage.
Red Yucca is used effectively in rock gardens and as a landscape accent, and I like to pair it with are Agave, Mexican Feather Grass, Sotol, and Lantana. It is best when used with other desert like plants and in Texas native designs because it uses low amounts of water much like many other Texas natives, making them natural pairings. It provides continued interest in the landscape with its almost year round blooms of rose pink to salmon. Even when not in bloom it does not lose its interest due to its long slender leaves that give it a grass like texture without being too fine. It can provide a great focal feature when allowed to fall naturally over a boulder, when placed next to a dry river bed, or looks great when planted in a bed topped with crushed granite.
In my experience, Red Yucca grows well in part shade or filtered sun if the landscape design does not require blooming. This can be advantageous as Red Yucca seed pods yields upwards of 50 seeds per pod. It is easy to grow Red Yucca from seed, and with enough moisture the seed can grow without soil. In fact, the humidity near the Texas gulf coast provides enough moisture in the air to begin the growth of Red Yucca seeds while they are still in the pod. This makes offspring once dropped even easier to root, so remove seed pods or flower stalks as soon as the flowers are no longer present to avoid additional future maintenance.
Hesperaloe parviflora ‘Perpa’ or Brakelights Red Yucca is a variety of Red yucca that features vibrant brake light red blooms. It is a compact new selection with more prolific flowering and exceptionally long season due to its tendency to not set seed pods. It can reach a height of 2 feet tall and is known to attract hummingbirds due to its cup shaped red flowers that are easier for the birds to get pollen out of and are highly visible.
