Becky, I have Firespike, Firebush (Hamelia patens), Salvia coccinea and Cape Honeysuckle (Tecoma) but the hummers don't seem to be attracted to them. I've seen a hummer on rare occasions at the Firebush but never at the Firespike, the Salvia or the Cape Honeysuckle flowers! If they arrive early in the year they love the Bottlebrush blooms but that tree is only in bloom December through April (with sporadic blooms once in awhile in May). In my yard, the hummers are attracted to the Pagoda flowers, Ixora, Pentas, Tropical Milkweed, Hoyas that hang in a tree and sometimes even Daylily blooms.
We see hummingbirds here in northern Volusia county sometimes beginning in March and they stay through August or September but they are always females ... I rarely see a male. I think it's a bit too cold here during winter for them, not enough plants blooming to keep them fed.
