This one is little right now - about 2 1/2 - 3" diameter. I potted it in a little Bonsai pot for right now - lots of room for roots. Like most babies it was in soil I don't like for succulents - it holds way too much water - so I made a mix that is very porous. I have several succulent leaves and a few cactus pups I just set on top of similar mixes and most are rooting nicely so I think this one will do well. Hopefully it will produce flowers and someone will be able to identify it perfectly.
I'm almost afraid to see how many plant names will change as DNA is used more for determining plant lineage. It will be nice having plants "better aligned" in taxonomy.
