Sedum x Rubrotinctum is more commonly known as the Jelly Bean Plant. It's a low growing evergreen succulent that readily offsets and grows up to 20cm tall.
I have learned the hard way that these little guys lose leaves incredibly easily ( just a little tap will often knock a few leaves off) but they also propagate very easily. So you can keep those fallen leaves and grow more plants.
The pot size is 6.5cm.
