Beaumontia grandiflora won't flower
I got this plant in trade several years ago, and It has had some hard knocks. One winter the door to the greenhouse blew open and it froze back to the soil line, another winter it lost all its leaves, etc. But finally, last winter I found a place where it was HAPPY, and it's putting on new growth like crazy---but I've NEVER seen this flower. Now that it's growing good, what should I do to encourage flowers? How much sun does it need, and how heavy a feeder is it?
