Hi there!
I started growing Monstera Deliciosa from seed a few weeks ago. Most of them are looking very green and healthy.
However, I got one funny looking guy, who has one thick White stripe down the length of the leaf on one side (picture attatched). I don't know, why this one is looking different than the others. I think it looks nice though.
Does anyone have any ideas, what may have caused this?

It's called a "sport" and is a genetic abnormality. It is nature's way of diversifying the gene pool and enhancing the survival of the species. Other leaves may or may not have the stripe. There is nothing you can do about it one way or another. Keep us posted on future growth.

Thank you for replying.
I'm actually pretty happy with the way it looks. It looks healthy as well, so if these stripes show up on more leaves, I would be happy about it.
