Dean McLellan sent this photo of the wall (limestone) at the front of his garden. The Sedum covering is growing luxuriantly into its second year. During the first year it was watered regularly, this year only occasionally. I have tried to do similar things in Scotland on other types of rock without success. I can only manage to get grass turf or heather turf to survive.
