I started Ruellia humilis this year, but lost them to a cold snap. I don't think they would be perennial in Calgary.

I would think that in zone 7 there is still time for them to root if they are moved.
Maybe move only half of them now? A mulch just before winter might help?

Thank you. I was also wondering if they would survive winter in zone 7 if it stays mild?
