Found growing along the banks of Little Cedar Bayou near where West Fairmont Parkway crosses it in LaPorte, TX. Only one plant still had flowers and these were past their prime.
Seen growing under and around the boardwalk over Dickinson Bayou in Hopkins community Park.
Non-native, but grow "wildly" all over Oakland, CA. This one was at Joaquin Miller Park
