Sedum lineare "Variegatum"
Here is another beautiful Sedum that I have been impressed with. It's hard to tell from the photo, but each linear, soft green leaf is outlined with cream. Sedum lineare grows to about four inches high in sun and well-drained soil and does not appear to be invasive, although it's so pretty, you just might want it to be. The flowers are not the show on this beauty, but they are yellow in case you want to know. This sedum is variously listed as being hardy anywhere from Zones 4-7 through 9.
