Sedum leibergii
Sedum albomarginatum
Variation in the number of floral parts of Sedum leibergii (5–7-merous) is unique in North American sedums. It has tiny rosettes of lax, long-spatulate basal leaves that mostly have shriveled by anthesis. Sedum borschii, which is often confused with S. leibergii, has primary rosettes, prominent at anthesis, that have obovate or elliptic leaves.

Of conservation concern.
Sedum albomarginatum is unusual in having woody roots. It is known from the Feather River Canyon of northern California. The white margins, formed from epicuticular wax, may not be as conspicuous on plants growing in shade.
