Looking at the stem I think you have a plant that has a virus.
Actually,if I remember right the seed had the virus and it messed up the Embryo...
If it's what I think you'll get random branches that look fused together and twisted.
I forget what it's called.
It actually makes for some cool looking plants.Parts will be normal and parts will be mutant.
I don't remember if it can spread to other plants.I don't think it does.
3 or 4 fused branches
See how the top has twisted leaves?Center vein is crooked comming from the fused fork/branch.
