I planted some small burnett on a gosh-awful reclaimed strip mine site 1 or 2 years ago, as an experiment. Zero lime or fertilizer, and the site has extremes in moisture. The burnett seems to be holding its own. I didn't think it would take the wet feet, but it is still there. I need to get a cage or two out there to get a better feel for how they are eating it. In those conditions, it does not seem aggressive enough to keep a solid stand, though; I will overseed with alsike clover probably, to fill in a little bit.
