Kay, I got tired of it and gave my white erubescens away this summer, but I would be delighted to send you Red Dragon.
pirl, if you decide to save the tubers wait until a frost just nips the foliage. If they are in a hanging basket the easiest way to get them is to just turn the soil out of the basket to expose the tubers. I usually take mine in around the first of November and it looks like it will work out that way again this year. Store them cool and dark and dry. In January I check on the tubers and if they are looking too shriveled I sprinkle a few drops of water on them and put them back until March when I start them into growth for the next season. Mine were originally grown from seed, but they develop quickly and are bigger faster if you start with a tuber.
I did cut it back in late November and put it on the porch in an out of the way spot. One day I spotted all new growth and now each plant (four in the pot) are a foot tall so I guess cutting it back to get it fuller would be the thing to do.
Cuttings didn't work well. Only one took and only time will tell if that one will grow into something worthwhile or die.
I'm blushing, lol. Time to look at mine and see how they are doing. I will get them ready for the greenhouse soon.
It is amazing how many cool plants can be overwintered as tubers if your zone is not warm enough to grow them year round. Gotta love it.
Kay, I think you could start it into growth anytime you can keep it from falling below 50 degrees at night and can provide good light. I would love to see what yours looks like after a growing season in your climate!
I will wait a couple of weeks until I am ready to start heating the greenhouse to pot mine up and won't be able to put it outside until April, but by then it should be up and growing well.
