Hedgerow princess destined to die unmarried?

This primrose, with its promise of spring, produces two kinds of flowers but only when an insect transfers pollen from another flower will it produce seeds - and I didn't see any flying insects around at the allotment today. It was Shakespeare in the Winter's Tale who wrote of 'pale primroses that die unmarried'. Apparently in the Middle Ages a concoction made from primroses was used as a remedy for gout and rheumatism, and infusion of the roots was taken for nervous headaches. The flowers were also employed in the preparation of love potions. Perhaps I should delve into the latter recipe more diligently...
