This is a nice plant, grows well and flowers like crazy under the right condition, which I can't give anymore unfortunately.
by the way, the buds have been growing larger fast and they are about to open now.
I see the light green buds turning yellowish and showing red. These flowers open rather reddish, then over the course of a couple of weeks or longer, the fantastic colors of tropical sunset (dark apricot or orange with red tips) kick in. Truly amazing!
