Marigold, I purchased LE Karusel a month or so ago from Lyndon Lyon. It arrived as a good size plant in bloom, and since then has grown and continued to bloom, with more buds forming. It's one of the prettiest plants I own. So from this limited experience, I would say it is easy to grow. By the way, I grow in natural light.

I ordered LE Karousel from the Violet Barn a couple years ago. Since I am not a Standard fan, I grow semi most, Karousel blooms easily. Many of them bloom when they are very young plants with the mother leaves..

Thanks for sharing your experience Judy, I think I'm going to give it a try.
