Cows and Marshwort

I wrote a piece about the cows on the marsh that may interest wildflower folk. For a while I didn’t question why cows were wandering about while Canary Wharf blinked on the skyline. Then I learned (Hackney Citizen last winter) that it was all about the creeping marshwort. this cow-based botanical project worked? I wouldn’t know marshwort if it slapped me across the face.
