I have a 12-18 inch flower with hairy leaves.?

Question

The flowers resemble a delicate buttercup, have yellow central pistil areas. The petals fall off every afternoon and new flowers appear the next morning. What is the name of this flower?

Answer 1

I believe you may have the same flower I have been trying to identify - and found this information listed at the source cite below.  The picture doesn't quite fit, but they are 12-18 tall, very hairy leaves and the pods are clustered at the top of the plant.  Apparently called Evening Primrose.  Mine are yellow - but there are other colors available.

Answer 2

Is it perhaps a type of Oenothera? There are a lot of yellow ones in the group (ie: Oenothera fruticosa, O. tetragona, O. erythrosepala...) and the flowers only last one day.

I think we badly need to see a photo.
