That is the most CONFUSING website I've ever seen.
Photo of Blue Elf, Title of Cosmic Commet, description for SEMPERVIVUM?!?!?!?
Here is what I have gathered from comparing the two:
1. Cosmic Comet has purple/red hues in stress, whereas blue elf only has at most, purple/blue.
2. Cosmic Comet is more of a upright/trailin/spindly form, whereas Blue Elf is clumping/matting form.
3. Cosmic comet is much less compact.
4. IMPORTANT: Cosmic Comet sends out an umbel (or umbrella) of blooms, whereas blue Elf only sends out blooms of 2-3 sets from cracks of the leaves.
Your photo may be wrongly labeled but I doubt it. You'll have to wait for blooms.
