Thank you for the comment!

Yep, kale is also part of the cabbage family and I actually included it in the post. It's in the upper right corner of the last image, but I guess I chose a bit of a strange picture for it ;)

I didn't know that about bananas, I guess that's because where I live all bananas are imported and thus all of them are underripe (if that word exists). What I know about most commercially available bananas around the world is not that they are all the exact same sort, but that they are all genetic clones coming from the exact same plant.
