These are absolutely magnificant plants. I start mine in March so they bloom late july. Has anyone tried to move them indoors under growing lights for the winter. If so how do they last. Sure would be nice to have them bloom all year in canada

I first purchased this in an 8" pot, which needed repotting after the first year. After 6 years of overwintering, dividing, repotting, etc. It just became too ponderous a plant so I let it go to ou... read more
