Someone gave me this plant this past spring. I potted it in a large pot with other plants. Didn't bloom at all over the summer. What an odd plant, I thought. It got very leggy, 3 ft tall. Finally, after the first frost in October I got a single bloom. Lucklily we had a warm November and I had a few more blooms by December. After 6 months I want to see some more results. I drug the large pot inside now to see what happens. The blooms do last a long time and they make great cut flowers - especially in December! What was a disappointment, is now a pleasant surprise.
They do best in cool weather so if you can keep it through the worst part of the winter, you should be pleased with it come spring. I'd trim it back good when I set it back out. (root the cuttings for more plants)
