They will, without any problem at all. I keep some of mine inside on a windowsill because they are slow developing from flower bud visible to flower opening (months!) especially if they are not warm. My greenhouse got down to -4 C last winter, which was no problem for the veltheimias at all, but they were very late opening their flowers. They really are quite tough. Good luck anyway.
Veltheimia virus?

Re: Veltheimia virus?
Thank you, I didn't know that and I don't think I'd have dared to try. I have never overwintered one before; I kind of cheated and bought my first plant in flower this spring. I have 3 plants now, assuming the replacement they sent for this one is virus-free, so I'm not sure they would have all squeezed onto a windowsill anyway and I may have to try leaving some in the greenhouse.
