Sweet Laura was offered by a lot of vendors for a few years, then I just stopped seeing it. There is also a form of S.L. with variegated foliage.
MM and TT were more than I typically will spend on a 2" pot- about $12 each. Now I'm really glad I did, they both are looking vigorous so far. I got them from Brent and Becky's, and they also have a peachy colored one called Inca Ice listed as hardy to zone 5. Lazy S's offers all 3 of them too.
