Grown at Palm Hammock Nursery
Palm Hammock Nursery, just south of Miami, grows a wide variety of orchids, begonias and gesneriads. This Seemannia was growing in a greenhouse, as was the plant with the flower here; a bed of S sylvatica was growing in part sun behind the greenhouses. A photo of a flower variant of the species (possibly a hybrid) can be seen here.
