Did you know?
Primroses were one of the first UK wildflowers studied for evolution — Darwin used their two flower types (pin and thrum) as a key example of how flowers enforce cross-pollination
More for experts
The two flower types (heterostyly) are controlled by a 'supergene' — a cluster of genes inherited as a single unit that ensures pollen from one type can only fertilise the other
Often confused with
Cowslip (nodding flowers on a tall stem), Oxlip (similar but larger, stooping flowers — rare ancient woodland specialist)
