If anyone is looking for Lemon Balm plants...I have tons and will gladly give you enough to start a good bed of it...I'm going to b ripping out a couple of the big patches that have taken over in about a month...so I will have plenty of root stock for anyone that want some. You can't kill it, it spreads well, you can mow the edges of a patch with the lawn mower - it will just be thicker...smells great and is useful medicinally and in cooking...I use it to border sheds etc so I can mow the edge but not have to weed eat..and it really does make things smell good!
