About Wild Hyacinth (Dichelostemma multiflorum) Dichelostemma multiflorum is one of several species in the Themidaceae sometimes referred to as Wild Hyacinth. The genus Dichelostemma was previously included with Brodiaea, and some sources still refer to it by that name. This species is a native perennial herb that grows from a corm. It is found primarily in inland northern California, from Mariposa County northward, where it is found in grassy and open places at elevations from 0-5,000 feet. This species is somewhat less popular for garden use compared with others in the genus, but it is a good choice for mountain gardens in the Sierras and Cascades.
