Nectar-rich flowers. Larval food plant for numerous butterflies, especially skipper species. Expect in particular Arizona Powdered-Skipper (Systasea zampa), the Gray Hairstreak (Strymon melinus), and the Erichson's White-Skipper (Heliopetes domicella).
There are 5 species of Herissantia native to the tropical and warm temperate Americas. Herissantia is named after Louis Antoine Prosper H_rissant (1745-1769), French physician, naturalist and poet, and crispa comes from Latin meaning "curled or wavy" in reference to the leaves.
Found on dry slopes, canyons, roadsides, and in desert-scrub communities, to 3,500 ft. in California, Arizona, New Mexico, Texas (and Florida) south into Mexico.
