This plant was donated to UNF as C. salignus by a nursery owner who found it at Jacksonville Beach. UNF staff is monitoring the plant to verify its identity and learn its tolerances. The genus Callistemon is very closely allied to the genus Melaleuca, a few of which are serious pest plants in south Florida. Fortunately, Callistemon species have not shown invasive tendencies in Florida.
