This is Lady’s Smock also known as Cuckoo Flower. It is a meadow and riverside field plant that flowers in the late spring. It is fabulous in salads as it has a tangy, peppery flavour livening up spring salads. Related to watercress, which I have planted a bed of in the nearby stream, both the leaves and the flowers can be eaten. This photo was taken on the east bank of the Rumbling Bridge gorge.
Since then I have planted a section of the stream woodland at Wychmoss with these charming wild flowers. Their seed pods, when ripe and touched, twist and fling the seeds quite far. So if I can keep the nettles at bay for a while next Spring I am hoping for a lovely display next to the hazel trees.
