Missouri Evening Primrose pods found on Roofs

A good number of Oenothera macrocarpa seed pods have been found 4 storeys up on the Stockwell Street Roofs. These large 4 finned pods have been blown in from a surrounding area. This illustrates that more research is required into how winds circulate around buildings and also how species can move substantial distances and heights. It is presumed that the seed pods have blown in from Greenwich Park. IMG_0413
