Yes, but they can take VERY little frost. Mine got killed in an
unheated polytunnel, but this is Cambridge. Keep it dryish in the
winter.

Are you sure it was absolutely dead. I have had D. meteloides
occasionally over winter outside in N Yorkshire. Everything dies back to
the roots and then starts again in late spring. In an unheated
greenhouse in Belgium I had one that lived for 5 years in a raised bed.

Worth noting that they are fairly poisonous plants. The perfume from a
couple of flowers will fill a greenhouse and hover flies love them.
