Should be opposite leaved, just like other jades. Must be some sort of fluke or mutation. I'm curious to see what this looks like, can you share a photo?

Emily...

Here is a photo of the strange side. About 4" tall but lower light here has kept it a dull green. I'm hoping that now spring is here it will silver up and get those nice red edges

That's very interesting, the stem is sort of zig zaggy. It looks like its just one leaf growing per node, and then they just switch sides every node, if I'm not mistaken

Also looks like the pair of leaves on top might be "normal", possibly reverting back to a non mutated growth. I've seen jades do that with other types of mutations
