General Landscape Uses:
Primarily recommended for natural landscapes, and wildflower and pollinator gardens, but may spread if not checked by physical barriers.
Ecological Restoration Notes: In peninsular Florida, this has mostly been found growing on roadsides and in other disturbed areas, where it can spread readily. It's role in native ecosystems is generally not clear, but it has been collected in pinelands (e.g.,
Cooley 6433 USF).
