Periwinkle ground cover

Question

What does periwinkle look like in the winter? Does it stay green? Do you need to mow? What happens if you mow?

Answer 1

Yes, Periwinkle does retain it's green color throughout winter in most climates.

I know in my own zone 4 garden it stays mostly green with some areas turning a dark almost burgundy color. It recovers nicely when the weather warms.
