I have this plant growing in my yard:

I've always just tried to keep pulling it out and mowing it. It started growing in the field near me and it turns out, in its second year of growing, the thing bolts - and it for SERIOUS bolts. It sends up a thick stalk about 5-8 feet high. The stalk is light weight and TOUGH. It lasts over winter and become something like a thick, velvety, woody bamboo stalk. I cut them all and cut off the dried seed heads (make excellent fire starters!) and clean the fuzzy dead leaves... and free bamboo stalks for my garden vines!
It is kind of exciting to realize you have something so useful just growing in your yard on its own.
