Snake’s head fritillaries, cowslips and dandelions at Clattinger Farm, Wiltshire 

Come the first two weeks of April, with the first of the cherry blossom billowing, the snake’s head fritillary will be pushing above the fresh shine of new grass. It is of some debate whether Fritillaria meleagris are actually native to Britain – some say they were introduced by the Romans – but they have a number of secure strongholds in this country and, if you can find the time to visit one, you will never forget it.
