You can prune it to the ground in late winter and it will grow from its
roots in the spring and flower in the summer.

If you prune it to the ground around here in late winter you'll kill
it.

This sounds right. When I pruned mine a little in September, it immediately
began sending out new growth. I wouldn't want to suggest that idea to the
plant when there's still a risk of temps in the teens.
