Frenchy, that is a pretty Rosemary plant you have. .
Odd but today I walked through the garden centers. They don't have a lot in yet but had a row of Arp rosemary plants. Makes me think spring is the time to get them established.
On my prostrate rosemary plant, I have been able to cover an attached branch with soil and get it to root. My problem is replanting the cutting. Not so much luck...
