Hi. Can you help me with theese succulents?
The first is probably a Sedum, perhaps Sedum spathifolium.
The second is likely an Echeverria, but I'm not an expert.
If you don't get a definite answer here, try GW's Cacti & Succulents forum.
yes, Sedum, and possibly Graptoveria (an echeveria - graptopetalum hybrid) 'Fred Ives', or an Echeveria.
You want them growing in a very gritty mix so the roots don't rot.
