I have a large semi circle of rocks and flowers in the front of my house. Several large rocks form part of the circle and I was looking for something that would grow around and over these rocks as a natural accent.
I friend of mine who is an avid gardener, suggest I plant some wooly thyme for this purpose and I have been very pleased. After a couple of years, there was enough growth for the thyme to begin covering the rock which looked very natural and appealing. It kind of reminds me of moss you see growing over rocks, but does not need shade or moist conditions to thrive.
