All sedum are supposedly edible, though yellow flowering species should be avoided based on mild toxicity.
http://portlandnursery.com/pla... This site lists the evergreen and semi-evergreen sedum varieties. Leaves can be eaten raw in salads, though some species can be bitter. If you find this to be the case, cooking is said to remove the bitterness. The suggested use is as a stir fry vegetable.
