Bulrushes

So I googled Bullrush only to discover it had one "r" and no mention of it being endangered or protected as I had thought !
I also discovered it is called "catninetails" or "punk" in the USA! Didn't know that either!
This patch grows at the side of the 12 th tee on The PGA Centenary Course so if you're watching the Johnnie Walker on TV next weekend, look out for it!
