What is your least favorite weed?
I have three candidates:
1. Catchweed bedstraw (Galium aparine) - also known as "velcro" plant. Sticks to everything, but is easy to pull.
2. Bur chervil (Anthriscus caucalis) - also known as "hedge parsley". Small white flowers produce little hooked seeds.
3. Tragia (tragia cordata)- also known as "noseburn". No redeeming qualities and as bad as stinging nettle.
I have a bumper crop of all three this spring.
What are you yanking out?
