General Comments:

Noted for fragrance.  Trichostema setaceum is similar but less common in central and southern Florida.

There are now at least 4 different Trichostema species being recognized in Florida.  Please get your plants locally given that we do not know how closely related these newly identified taxa may be, and we do not want to accidentally cause introgression between closely related species and subspecies.
