I only know of one place within miles of Whitstable where I can find Early Purple Orchids - in a small area in nearby Clowes Wood.
I've seen them as early as April, but each year they seem to flower later and, despite having been on the lookout for weeks, I had to wait until today to finally spot any.
Better late than never, but I think the 'Early' part of the name might need reconsidering...
