Hesperaloe (genus)

This profile represents Hesperaloe at genus rank. [Kew](https://powo.science.kew.org/taxon/30050847-2) accepts the genus. No species, cultivar or planting material is chosen, and no universal dimensions, hardiness, water requirement or measured fire performance are assigned. ## Napa County — printed source context [Napa County](https://www.napacounty.gov/3373/Defensible-Space-Firewise-Planting) prints Hesperaloe / Red Yucca under Perennial. The source gives a bare genus name paired with Red Yucca. It does not print a species or selection. H. parviflora remains a separate narrower record, and the common name does not identify it as the publication’s specific assessed material. The Napa tag is a qualified documentary association at the printed generic-name scope. The source’s biological circumscription, intended material and individual-member assessment remain unresolved; this is not an assessment of every species, hybrid or cultivar. The catalog type organizes the profile without establishing a uniform growth form. Napa publishes no numerical ignitability score for this entry. Keep other regional ratings separate, identify the actual plant before selecting placement, and follow local guidance for plant spacing, watering and removal of dead material. Napa emphasizes maintenance and site conditions; no plant is fireproof.
