There are 2 varieties in Palafoxia arida, Desert Palafox
Palafoxia arida var. gigantea, Giant Spanish Needle, (AZ, CA);
Palafoxia arida var. arida, Desert Palafox, (AZ, CA, NV, UT).
Comments: Giant Spanish Needles was first described on sand dunes west of Yuma, County, Arizona. Desert Palafox was originally classified as Palafoxia linearis which is a Mexican species also called Desert Palafox, but one that does not reach as far north. Perhaps additional research will provide insight into the relationship between these two species, if in fact they are separate species.
Be aware that Palafoxia arida and Palafoxia arida var. arida and Palafoxia arida var. gigantea share the common name Desert Palafox.
Giant Spanish Needles, Palafoxia arida var. gigantea small showy pink tubular florets, their seeds and plants may be visited by hummingbirds and/or small mammals including rodents and granivorous birds in search of food, nectar, shelter and protection through cover.
Beneficial Value to Butterflies, Bees and Insects
Giant Spanish Needles, Palafoxia arida var. gigantea, small showy pink tubular florets and their plants are likely visited by butterflies, moths and other insects in search of nectar and/or other food.
The genus Palafoxia is in honor of perhaps Josè Rebolledo de Palafox y Melzi (1776-1847), Duke of Saragossa. However, a paper published by Hervè M. Burdetin suggests that the first choice name was originally to honor and commemorate Juan de Palafox y Mendoza (1600-1659), who was a bishop and founder of the University of Mexico. The paper further suggests this is so because the other Palafox, Josè Regolledo de Palafox y Melzi became a national hero and the attribution was transferred to him.
The species epithet "gigantea" is a celebration of its large size.
Desert Palafox, Palafoxia arida is used as a dye by southwestern United States indigenous peoples.
