You never know what you might find on a trip to the greenhouse. This week I managed to frighten a mother Junco hyemalis - Dark-eyed Junco off her nest in the vertical greenwall experiment. On the upside, I got a shot of the chick.

Additionally, when dealing with the cold frames I was faced with an astonishing infestation of Marchantia polymorpha, the Common Liverwort. This species of liverwort, a plant somewhere on the evolutionary spectrum between algae and mosses, is found around the world on wet stones and as a greenhouse pest. I think it looks like a plant from another planet or at least another, earlier point in history (which it really is)!
