Hi there
Looks lika a mutation surely..
I can’t imagine it will get much growth there as it would struggle to support it 🤔
It will be interesting to see how this turns out ..
Best of luck 🌱
More common than what you think. Just some of the Gene's for the new branch made it's way to the leaf. Also had leaves that had up to 20 points sticking out everywhere. You have an extra bud site.. Cheers
