(Primula elatior )
Oxlips appear similar to both primroses and cowslips, being halfway between the two in terms of size. For this reason they were once thought to be a cross between the two (see fact below). Cowslip flowers, however, are a slightly are deeper shade of yellow whilst the primroses only has one flower per stalk.

Did you know...
For many years it was thought that the oxlip was cowslip/primrose hybrid. It wasn't until 1842 that the botanist Henry Doubleday did some breeding tests that suggested they weren't. To double-check he sent some of the seed he'd used to Charles Darwin who tested it himself. When Darwin got similar results he wrote a paper to confirm Doubleday’s work.
County flower of Suffolk.
Here it is the signature flower of well-established woods on the East Anglian boulder clay (where it replaces the primrose).
