This species comes in two cultivars. My favorite is called 'Blue Spruce' and has a color resembling the tree of that name. The other, pictured here, is Sedum reflexum 'Angelina', a lighter green version which gets reddish tips in the cold or in adverse conditions, as seen in the pictured plant. I have seen both as escapees, but I do not have good photos of the other cultivar as such. The plants can be somewhat easily mistaken for Portulacca grandiflora if not flowering.
