I grew this plant last year in a fake half whiskey barrel planter, and took cuttings at the end if the season. Only one cutting rooted, but I have it growing in a 1 gallon nursery pot under lights at my office. It has been just sitting there for weeks, healthy but not doing anything, then this morning I came to work and there are 6 inch long new branches all over it that were just buds last week. I guess it thinks it's spring!
I'm not real sure how to keep it under control indoors for 4 more months until I can set it out. Just keep pinching the growing tips out? Maybe I can take some more cuttings...
I hope it blooms more this year. It should bloom continuously once it starts, but mine bloomed big in June and was about to bloom again in late fall when the cold weather came. It's a zone 10 plant; maybe it gets confused by 16+ hours of daylight.
