Common Name: Hogweed
Scientific Name: Heracleum sphondylium
Heracleum sphondylium, commonly known as Hogweed, is a herbaceous perennial or biennial plant of the family Apiaceae. It is an umbelliferous plant, in the same group as fennel, cow parsley, ground elder and giant hogweed. Umbelliferous plants are so named because of the umbrella-like arrangement of flowers they produce. reaches on average 50–120cm of height, with a maximum of 2m. The leaves can reach 50 centimetres (20 in) of length. They are pinnate, hairy and serrated, divided into 3-5 lobed segments.
This plant has pinkish or white flowers with 5 petals. They are arranged in large umbels of up to 20 cm of diameter with 15 to 30 rays. The peripheral flowers have a radial symmetry. Flowering typically occurs between June and October. The flowers are pollinated by insects, as umbellifers attract a wide array of bees, wasps, flies and beetles.
www.uknature.co.uk is a website dedicated to showing the immense diversity of UK nature and wildlife. Our vast range of habitats, from lowland arable to snow covered mountains, from storm-ravaged coastlines to peaceful inland freshwater lakes and rivers, from dry, sandy heaths to deciduous and coniferous forests, all these habitats contribute to the abundance of UK nature. We have wild birds in huge numbers either residing or visiting our shores (597 recorded species as at July 2013) and we must also not forget the humble back garden with its grass lawns, flower beds filled with nectar rich flowers, shrubs and trees, all designed to attract huge numbers of insects such as bees, moths, butterflies and hoverflies; and finally the small ponds which provide safe havens for frogs, toads, newts and even slow worms and grass snakes. www.uknature.co.uk is the showcase for my personal passion, photographing uknature in all its glory. I sincerely hope you all enjoy the fruits of my labours.
