Evening primrose

Description:

The plant was tall. The leaves form a basal rosette at ground level and spiral up to the flowering stems; the leaves are dentate or deeply lobed (pinnatifid). The flowers open within less than a minute in the evening, hence the name "evening-primrose", and are yellow.

Habitat:

Native to America. 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.

Notes:

I have also seen this type of plant in Belgium, most likely started as garden plant and then spread to wild parts.
