Buttercups – numerous yellow wildflowers
Ranunculus includes various quite superficially similar species, which flower in late spring to summer with five yellow petals. The two pics below show the wildflowers in short grass in open spaces.
Locally in Seaford we have bulbous buttercup, Ranunculus bulbosus, which likes chalk and can be identified by its reflexed sepals.
Ranunculus repens – garden weed
Creeping buttercup can be differentiated from bulbous buttercup by its creeping nature, leaves and sepals, although the flower itself is much the same.
