tell me...

In the past few days I've seen two t-shirts with the same image on them. It's a plant of some sort, with five leaves - two on the bottom and two above them, with a stem in the middle, and a leaf on top. The top right hand leaf is a different color - red on the last shirt I saw, and possibly red on the first. What the hell is this? It's driving me crazy. I'd include an image, but if I could find it, I wouldn't need to post this. Help!
