Below is one of the wild flower lawns in my West Sussex garden today.
Two other species are Southern marsh orchid
and ten or more Common-spotted orchids
Yellow Rattle has spread around nicely too.
Insect life is intense and the whole lawn area is species-rich and alive with colour.
A beautiful result from benign neglect.
