Evening primrose

Plant found growing in disturbed soil near recent construction area and community garden. According to Wikipedia, "In the wild, evening-primrose acts as a primary colonizer, quickly appearing wherever a patch of bare ground may be found. It tends to germinate in disturbed soil, meaning that it tends to be found in poorer environments such as dunes, roadsides, railway embankments and wasteland. It often occurs as a casual, eventually being out-competed by other species."
