Further Information

Notes (MWS) A common species of waste ground and gardens.

As the common name implies, the yellow flowers open in the evening. The speed at which they open is quite remarkable, the petals expanding within a few seconds. Watch this in July between 8 and 8:30pm. The flowers shrivel in the following day's sun.
Wildlife Gardening Although not even a European plant, it is commonly grown in wildlife gardens as the seeds attract Goldfinches.
