Hesperaloe parviflora Arizona Sunrise - Red yucca

Hesperaloe parviflora 'Arizona Sunrise' is a plant from the agave family. This selection stands out with its yellow flowering, an unusual colour for a Hesperaloe. This perennial grows in dense rosettes of long, evergreen leaves that are slender and arching. From the centre of the rosettes, a long and graceful flower spike laden with small tubular flowers of a buttery yellow emerges in summer. Despite its exotic appearance, it is a plant for extreme climates, capable of withstanding our damp, cold winters and snow in well-drained soil. A must-have!

Native to the Chihuahuan Desert, straddling Texas and Mexico, reaching up into the Texas mountains, which regularly experience severe frosts and snowfall in winter, and arid summers, Hesperaloe parviflora is a plant adapted to extreme weather conditions. It is an elegant and very hardy plant which can flower under scorching heat, without water, as if unaffected by its environment. The cultivar 'Arizona Sunrise' differs mainly in the colour of its flowers. This fleshy, herbaceous and perennial plant has rhizomes capable of producing suckers, but it lacks above-ground stems. It forms a basal rosette, 40 to 60 cm tall and at least 60 cm wide, spreading sideways over the years to eventually form a thick groundcover. The leaves are pointed, narrow, linear and rigid, channelled in shape, prickly at the tip, and edged with twisted filaments. They persist in winter. The spectacular flowering occurs from June to August. A flower spike 1.20 m tall, branched, slightly arching at the tips, emerges from each rosette. Along its branches, it bears numerous small, tubular and trailing, fairly pale yellow flowers. This nectar-rich flowering attracts many pollinating insects. The plant is hardy to -15°C in well-drained soil, much more in dry soil in winter.

Hesperaloe parviflora 'Arizona Sunrise' is a unique plant for its architectural silhouette and robustness. A boon for rocky or sandy gardens, where soil is scarce, it is ideal for forming large flowering borders all summer, structuring a large rockery or an exotic bed, or even for greening a very dry area of the garden. It can be planted alongside agaves and carpeting plants (Teucrium chamaedrys, Sedums, houseleeks). Its architectural quality blends well with the wild charm of grasses (Stipa tenuissima or S. barbata). Very floriferous plants such as Gaura, Nepeta Six Hills Giant or the indestructible Erigeron karvinskianus can accompany its flowering throughout the summer.

In New Mexico and Arizona, this species is commonly planted as a large groundcover by landscape professionals who use it to replace lawn on roundabouts and central reservations, for its exemplary low-maintenance nature.
