Have not started any more, it was a very small area that was unusable, over the last several years I have moved the plants around, added and deleted, its been really fun. There was a short time when the squirrels and chipmunks tried to wipe out the sempervivums over the winter, luckily they were not successful (not so much for my neighbor, they wiped out a 2x3' area of sempervivums), the following winter I added a plastic netting that seems to have taken care of the problem just remove it in the spring. A few of the plants earlier in the season, the Delosperma is still intermittently blooming.
