Remember this stuff?
I think we used to call it "arrow grass" or "dart grass" as kids. I’m sure that you were just the same as me, and used to pull the heads off the plant and throw them at friends. They always stuck best to woollen sweaters – they were hopeless on cotton and polyester shirts. I seem to remember some story along the lines that the one that you would marry was the person who you could get these things to stick to. But then I’ve heard that about cleavers too, and it never worked for me. Not yet anyway.
Me and my friends had a lot of fun with arrow grass as kids.
