Well my t. variegata just lost most of it's leaves #$% Seems like the sun is already intense here as well, so moving them into a shadier side of window... and probably have to source another variegata, i really want to see that flower... lol
the t. guaiensis is handling direct sun, though...
the calochila(um) of mine had been on the shadier side already to keep from blasting, so far flower has lasted maybe a week or so, not bad...
