I had one of these 5 or so years ago that bloomed while still a fairly small plant. Hummingbirds loved it.
This year I have another one that I got in March or April. It's a water hog and a grow monster-- it's in a 14" pot right now and still needs water every day.
But no flowers! What in the world is wrong? It is getting full sun and lots of water, growing like crazy. Surely it should have bloomed by now?
