Gorgeous color! They are a bit picky about light exposure before they bloom. I don't really try to get mine to bloom but, they seem to start budding a couple weeks after I bring them indoors for the winter. Shorter daytime hours I guess?
That's probly why it hasn't bloomed before 🤔 steady regular lighting. (?) Similar to poinsettias, you are supposed to change their lighting schedule. Mine just do what they do,.. I don't try to force them. But they are such a pretty flower. 😍
