Sedum
We have three or four different kinds of SEDUM on Rock Hill Garden, mostly varieties of Stonecrop. They spill down the hill, intertwining with each other. The yellow variety below kept its color all winter long and was so striking peeking out through the snow. It was a spot of cheer when winter dragged on. Sedum is easily transplanted and we've moved slips of it to a flower bed near the street and others to mingle in a pot of Hen & Chicks.
