I am trying to match a name to a plant I have owned twice now. Description as best as my nonbotanic background can provide: Flat leaves very close in shape. thickness, etc to leaves on a jade plant, but velvety to the touch. Plant shape and growth pattern very close visually to that of a jade plant. Outter rim of leaves sprout tines? thorns? clawlike or toothlike extensions. The larger a leaf, the more claws it has. Claws are not hard like cacti spines, but still have a rigidity to them and are not squishes without breaking. Sorry, I cannot remember the actual color of the plants, and have no pictures. Could not find picturse of one on the internet though I image searched for succulent plants, Echeveria, and Crassula (among other combinations). Nothing I found looked close enough. What I would want to know: what is it? how do I keep them alive if I find one again?
