Latin name: Fritillaria meleagris. Now rare, it flowers in April and May. Its wetland habitat was subjected to great pressure during the "Ploughing for Victory" campaign of the second world war and further drainage for agriculture has reduced the flower to just a handful of places - North Meadow contains 80% of the UK's entire population of Snake's Head Fritillaries over a 110 acre area.
