I live in Mystic, CT. I planted the Witches Hat in full sun in my garden and it grew vigorously but never bloomed. I didn't give up, though. I dug it up, potted it, and placed it in a west facing window. Again, it grew vigorously, so much so that I trimmed it back some. It's back again, and I plan to try it in my garden again this year. Any advice to encourage blooming? I'll attach a current photo.
