Silverweed flowers from May to August with single yellow flowers on village greens, roadsides and damp trampled grassland. It spreads by long, above-ground runners, and its pinnate leaves are silvery-hairy underneath. The open flowers provide pollen and some nectar and are important for small wild bees. British measurements give around 6 micrograms of sugar per flower per day, around 118,141 pollen grains per flower and a nectar yield of around 0 kilograms of sugar per hectare per year.
