Britain in bloom

It's variously known as cow-weed or cow parsnip, alderdrots, bilder, caddy, eltrot or old-rot; kirk, chirk or keks; and rather delightfully, limperscrimps, and it's in flower right now on roadsides, hedgerows and field margins right across the country:

Hogweed (Heracleum sphondylium) gets its most common name from the apparently piggy smell of its blooms, which are far less lace-like in appearance than its cousin the cow parsley that flowers earlier in the year. A sturdy, architectural umbellifer, it's related to the tiny pignut I saw in bloom across swathes of Cumbria last month, and also to poisonous hemlock; angelica, with its huge, more globe-like flower-heads; and wild carrot, which often has a single red flower in the centre of its umbels.

Look up 'hogweed' online and you'll find far more space devoted to giant hogweed, its non-native relative, than our beautiful common sort – small wonder, I suppose, as contact with the giant kind can cause appalling burns. Our own variety has a specialist invertebrate, the hogweed picture-wing fly, which parasitises it; its open flowers with their exposed nectar are also loved by soldier beetles, hoverflies, bees fruit flies and many other creatures.
