Papaver ruprifragum seeded itself here on the gravel area when I used to sell plants from this patch.
The bees find them first thing in the morning, before the petals have even uncrumpled themselves - fourteen flowers, seven bees this morning....
..sometimes three bees in each flower. We reckon to have about 2000 flowers from this clump each year!
Having been pollinated early in the morning, the flowers drop their petals throughout the afternoon, but for the whole summer each day brings a dozen or more new flowers.
