i am not sure what you are asking...like what CAN grow here?
i have probably 45 different species/hybrids in my trees mostly in the phal and den Genus. i have nobiles and den phal hybrids and schoms all in many trees. Onc as well and i am also having SOME luck with catesetums on a palm trunk
if you are asking for the ones that show up on their own, i have only seen ground orchids and enc tampensis
