I've had this growing in a pot in partial shade in my cold-winter climate for 1 1/2 months. It's in full bloom already, though it started out from a very small pot. I have yet to try overwintering it inside, so I don't know how it will do then, but so far it's been blooming earlier and more prolifically than most tropical plants do here.

I live in the Tampa area and this plant is wonderful, It is a quick grower to about five feet in two years. I have nine of these plants and have seen no sticky leaves or thorns. They will take a light frost and bloom continuously from early spring to fall. They come is several different colors from light purple to deep red. One of them did get a few mealybugs but a quick spray and they haven't returned.

I have to say I'm neutral about this shrub. I think it has it's good points & bad ones. The leaves are sticky - sort of like petunia - which I don't like, & as it gets bigger, there are sharp thorn-like projections from thicker branches. Still, I continue to grow it because it's an unusual plant & grows in my zone 7b-8a area. I have had it for 7 years now. It's against the west side of my house for added protection. Mine even set seed & ripened last year, but I'm not sure how viable the seeds are until I test them.
An unusual surprise cold snap in April appeared to kill it, but it came back from the ground level. It would look nice espaliered against the wall which I plan to do now as the growth can get quite rank.
I had hoped the blooms would be larger & more of them but perhaps it's to do with limited sun as the other house shades it too early in the day. I might move it for that reason. But I'm still happy with it & pleased that I'm growing a shrub that's not supposed to grow in my zone. I know there are other varieties of Iochroma that have larger & more attractive flowers & if anyone can find those, I'd highly recommend them.
