Unwittingly I have aped in a very minor way Cleve West at Chelsea. I missed some parsnips and have let them go on to flower. As many other umbellifers (Apiaceae), they attract hoverflies. Hoverflies are invaluable predators of aphids in the garden. They lay their eggs in them and the larvae then eat up. I was pleased to get these close ups as the 120cm stems were more than swaying in today's winds. Ladybirds seem to like to be on the flowerheads, be they in flower or set seed.
