“…The flowery May, who from
her green lap throws
The yellow cowslip and the pale primrose.
Hail, bounteous May that dost inspire
Mirth and Youth and warm desire…”
~ John Milton. Song on a May Morning [partial]
Cowslips are a later flowering cousin of the primrose. It was once so common that it was strewn along paths at a wedding. Now in sharp decline you can help boost the numbers by planting clumps in a cottage-style garden.
