Hi Fandog, welcome to GardenWeb!
I have no idea (though I'm sure somebody will,) except that it looks succulent-ish.
May I ask, what's the potato thing in the pot? Curiosity about that is why I'm here babbling to begin with.
Do you think your jade plant is getting enough light?
at first look i thought it was a pepperomia... but then the trunk made me think... eh, not so much.
Its growing tip and waxy leaves remind me of some sort of ficus or fig.?
OK, I DID say welcome to Fandog twice. For some reason your name didn't change colors (visited link.) Should have checked when it felt familiar, not trying to welcome you to death!
I think that's some kind of ficus. Hubby's Mom bought him a bonsai style ficus (with a caudex... not sure how they force a ficus to make a caudex) that looks similar to yours.
Just a guess but I'm thinking possibly ficus deltoidea.
The leaves don't have a delta shape in the pic but perhaps it's still early and in time will look more like the ones in the image search I conducted a minute ago.
Could be wrong....but for now that's my guess. :)
