This is an extremely old thread, but I am writing this just so anyone who reads this, I hope to clarify this a bit:
Sedum Little Missy, which is actually Crassula pellucida subsp. marginalis 'Petite Bicolor', is a crassula.
Sedum anglicum Suzie Q is a variegated variety of Anglicum.
Easiest way to differentiate the two is by leaf shape:
-> Little Missy usually grows two leaves per node, whereas Suzie Q generally grows in rosette shapes (sometimes will also make 2 leaves per node, but this usually doesn't happen a lot)
-> Little Missy's leaves are much thinner, and "triangle" like, more acute, whereas Suzie Q's leaves are chubbier, slightly more elongated, thicker, and rounder.
-> Suzie Q is much more unstable than Little Missy, so generally, when looking at large colonies of Suzie Q, you may find many "variations", unless the specimen is kept very well trimmed and cut. Some examples are half moon, albino, reverted, reverted/variegated etc. Little Missy is generally more stable, and rarely has fully albino leaves, but occasionally puts out reverted stems.
Do note that because of the unstable-ness of these 2 varieties, it is best to remove reverted stems or rosettes from specimens as they grow to make sure the reverted ones do not take over. Albino rosettes/stems are technically "parasites" because they do not make their own food, they survive only from taking nutrients from the parts of the plant that have chlorophyll, so, it is also best to remove those, unless you like that look of no chlorophyll.
