You have provided almost as much information as the person asking what
size tires go on a blue car.
However, try searching "Evening Primrose" and see what pops up

A friend gave me a plant which produces many yellow single cup shaped
flowers at every sunset .
The flowers fade very quickly lasting only one night but they are
replaced with a new crop at every sunset. I live in the North East of
England.
Can anybody tell me the name of this plant please?
Thank you
Tom
