Hesperaloe parviflora (Red Yucca, Red Hesperaloe, Coral Yucca, Red Flowered False Yucca, Samandoque)


Michael's Opinion

Hesperaloe parviflora which blooms throughout the summer months is an easy care, drought tolerant plant. It has been found to tolerate the dry winters of USDA zone 7 and to USDA zone 6 in moister climates. It is similar to Yucca in character however the foliage is often narrower and the blooms red instead of creamy-white.

Description and Growing Information

General DescriptionAn attractive landscape plant featuring coral red flowers during the summer months and clumps of thick green foliage.
ID CharacteristicHesperaloe parviflora can be identified by its foliage which is similar to that of Yucca except that the leaf apices lack a spine Its coral red flowers that resemble lilies are quite distinct
ShapeGrows in clumps or mounds of succulent grass-like, stemless plants.
LandscapeCan be used as an accent plant, in xeriscaping or to attract hummingbirds. It is extremely drought tolerant and is used in many southwestern gardens.
PropagationSow untreated seeds in flats by moistening the media and gently pressing the seeds into it. Keep the flats in a cold frame until the following spring. Once the seeds have sprouted wait 6 months before moving them to full sun light.
CultivationMinimal maintenance is required such as removing the spent flower stems. It requires full sun and supplemental irrigation in arid environments for best flowering; however, overall it needs minimal water as it is very drought tolerant. It prefers a soil pH of 6.8-7.2.
PestsAphids can be problematic during bloom.
Notable SpecimensDenver Botanic Gardens, Denver, Colorado, United States of America.
HabitatGrowth restricted to Mexico and the lower Rio Grande Valley and Texas. Found on prairies; rocky slopes; mesquite groves on well drained sand, loam, caliche, or limestone.
Bark/Stem DescriptionThe plant is stemless.
Leaf DescriptionThe simple, glaborous leaves have parallel venation, ciliate margins, acuminate apex and a truncate base. Foliage can be described as thick green rounded threadlike clumps or blades of about 60 – 90 cm. Leaves produce a curly white filament along its margins similar in character to Yucca, but lack the spike at apex found on Yucca's.
Flower DescriptionThe bisexual, coral red, bell shaped flowers are produced in early-mid summer with the flower spike resembling tall wands: flowers are about 35 mm in size. To encourage flowering, full sun and supplemental irrigation is recommended.
Fruit DescriptionThe black seeds about 3 cm in length can be found in multi-chambered capsules about the size of a ping pong ball held aloft on 1 m stems originating from the centre of the plant.
Colour DescriptionFoliage is dark green, while flowers are coral red. However in the winter the foliage takes on a plum coloured hue.
Texture DescriptionFoliage texture is similar to leather and fibrous along the edges.
