Last week I found an arum lily behind our garden fence. On Sunday afternoon I found another fine specimen growing in the shade of the lime tree walk in our nearby Linden Field. I had gone there to photograph the lime trees coming into leaf, and the avenue was a haven of leaf shadow and dappled light, and wonderfully cool in our unexpected heatwave. There was also the heady whiff of wild garlic. The plants whose leaves I had been cropping earlier in the year were bursting with white star flowers. You can eat those too. But you definitely can’t eat the arum lily, also known as Cuckoo-pint (pint to rhyme with mint), Lords-and-Ladies, Parson in the pulpit and Willy lily – though the roots were apparently once crushed to make household starch for crisping up Elizabethan ruffs (Richard Mabey Flora Britannica).
