I returned to my old stomping grounds this afternoon, and to my foolishness, I was shocked to see how much more lesser celandine, Ranuncus ficaria, there was along the floodplain of the Olentangy River. In this area alone, there were at least 30 virginia bluebell plants just two years ago. Today? There was ONE PLANT. This species is such a nasty, agressive invader of floodplains, it just makes me sick.
