Hesperaloe parviflora - Red Yucca

Hesperaloe parviflora is sometimes called Red Yucca due to its relationship with yuccas and its dazzling flowering. It is an excellent plant for dry or even arid soil, capable of withstanding both water scarcity and cold, and one of the most beautiful representatives of the agave family. Less imposing than large agaves, this perennial develops in a rosette of tough, thin leaves, a bit austere, but surpasses its close relatives the yuccas with the delicacy and liveliness of its summer flowering, in a bright salmon red. In New Mexico and Arizona, this species is commonly planted as ground cover by landscape professionals who use it to replace grass on roundabouts and medians, for its exemplary drought resistance. The Red Yucca, easy to acclimatise in many regions, is one of the few plants capable of flowering in the summer in hot regions (such as the Mediterranean) where many plants suffer in heat and drought and which can often be dull at this time of year.

Hesperaloe parviflora is native to the Chihuahuan Desert, spanning Texas and Mexico, and up into the mountains of Texas - which regularly experience freezing temperatures and snowfall in winter, and arid summers. It is a perennial plant adapted to very harsh climatic conditions. Both elegant and generous, the red yucca seems unaffected by its environment. This perennial succulent has rhizomes capable of producing suckers, but it is devoid of aerial stems. It forms a basal rosette, 40 to 60 cm (15 to 24 in) tall and at least 1 m (3 ft) wide, spreading laterally over the years to eventually form a thick ground cover. The leaves are evergreen in winter. They are narrow, pointed, linear, and rigid, gutter-shaped, with sharp tips and twisted filaments along their edges. Spectacular flowering occurs from June to August-September. A branched floral stem, 1.20m (4 ft) tall, slightly arched at the ends, emerges from each rosette. It bears numerous small tubular and trailing flowers in a beautiful shade of salmon red to coral along its branches. These honey- and nectar-rich blooms attract many pollinators. After pollination, a few globose fruits form, opening at maturity to release tightly packed black seeds. The plant is hardy down to -15°C (5°F) in well-drained soil, even lower in dry soil during winter.

Hesperaloe parviflora is a boon for dry, rocky, or sandy gardens where soil is scarce. It is ideal for creating large flowering borders all summer long, for structuring a large rockery or an exotic bed, or for brilliantly filling an unrewarding area of the garden. It can be planted as a solitary specimen over ground cover plants (e.g. Teucrium, Thyme, Sedum, Sempervivum) or associated on a dry slope with small shrubs for dry soil (Hertia cheirifolia, Hypericum olympicum), light grasses (Stipa tenuissima or barbata), lavenders, and rosemary. Highly floriferous plants like Gaura, Nepeta Six Hills Giant, or the indestructible Erigeron karvinskianus will accompany its flowering throughout the summer. Easily create a very colourful scene in summer by combining it with the Amorpha canescens, with its blue-violet flowers, or with trailing sedums, Caryopteris, or Afghan salvias.
