Shiso leaves. Grew them to put in lettuce wraps of Korean bulgogi. I think they taste awful, but they're supposed to be an acquired taste. If you're thinking about growing them, do it in a pot. They're supposed to be a bit invasive. http://www.capeandislands.org/post/leafy-japanese-herb-indescribable-taste-shiso#stream/0
