The primrose has a secret weapon when it comes to pollination: heterostylous flowers, which means the flowers have two kinds of style. Some are thrum-eyed, with a prominent ring of pollen-bearing anthers positioned above the style; others are pin-eyed, with a protruding pistil above the anthers. This two-way arrangement ensures pollen adheres to the furry bodies of visiting pollinators within seconds, ensuring plenty of viable seeds. Charles Darwin(1809–82), who spent 30 years breeding and hybridising primroses in order to understand more about genetics, pointed out these dimorphic differences to The Linnean Society on November 21, 1862.
Long before Darwin presented his paper, nectar-gathering bees had been busy producing a great variety of differences in wild populations. John Gerard listed several in his Herball of 1597, including a green double, and Elizabethan gardeners held such curiosities in high regard. There were hose-in-hose flowers (with one flower set inside another), which were named after the habit of Elizabethan noblemen of wearing two pairs of hose to keep warm in winter, and Jack in the Greens, when flowers sat in a ruff of foliage not unlike an Elizabethan lace collar.
