Dianne, you didn't originally list this one. You asked me to create an entry for Sedum 'Golden Glow,' and the one I found on the Web was Sedum adolphi 'Golden Glow.' I hadn't seen your photos at the time I created the entry.
Stonecrop is merely a common name. The genus Sedum no longer has 300 species. Many of its species have been redefined as species of other genera. Sedum rupestre has become Petrosedum rupestre subsp. rupestre.
Lemon Ball is still a Sedum (Sedum mexicana).
I can create a new entry for Petrosedum rupestre subsp. rupestre 'Aztec Gold' and move your photos there, or I can move them to Sedum mexicana 'Lemon Ball,' but the latter is said to spread to 24 inches. Is that true of your sedum?
