Nice little plant. Looks to me like Sedum morganianum (burro's tail). I think it needs more sun, growth should be a bit more compact. Could use faster draining soil too. Lena

I would imagine that room doesn't get below freezing; most succulents will be just fine in temps as low as 50*F. BUT, it is important that it drains well. If not, it will stay too wet for much longer in colder temps, and that could cause problems for the plant. It needs to be watered when the soil throughout the pot is almost dry - so it all depends on potting medium. What kind of soil is it in? What kind of light can you supply?

Well I think you have something fairly rare and special:-) I am not 100%, but I am a 20 plus year collector who spends tons of time succulent shopping online and I'd bet money on it! Even if I am wrong, you'd benefit from following the growing culture of the Grapto. mendozae. Search for info on Graptopetalum and Echeveria, they are similar, then look to cover these 3 topics. Soil mix, watering habits and light exposure. Then move on to cold/heat tolerance (hardiness) and propagation. Most of what you learn on this plant should transfer to almost any succulent. Enjoy!

I believe it is a echeveria agavoides, possibly Martin's hybrid. It is pretty. For care it is like all succulents, well draining soil, water only when dry preferably with rain water. Chemicals in tap water can be harmful. Acclimate to the sun slowly to prevent sunburn. Here is a photo of mine after some sun exposure.
