I planted it on May 27th and it's still pretty small, but I was looking at the leaves and there's purple on the outside of them. Is this a good thing or a bad thing? It's not a lot of purple...just a little on the outside. Sorry no pictures, I don't have a camera. Edit: It's still in the pot, not close to being put in the ground yet. It's first sprout was on May 29th.
