A month ago I took photos of the Giant Hogweed at Woolston Eyes, Warrington. Back then the plants were in full bloom - now they have gone over but still produce interesting and architectural pictures.
Heracleum mantegazzianum, commonly known as giant hogweed, cartwheel-flower, wild parsnip, wild rhubarb, giant cow parsnip, or giant cow parsley, is a plant in the family Apiaceae. It typically grows to heights of 2–5 m (6 ft 7 in–16 ft 5 in), sometimes reaching 7 m (23 ft). Except for size, it closely resembles common hogweed (Heracleum sphondylium), Heracleum sosnowskyi or garden angelica (Angelica archangelica). It is phototoxic and considered to be a noxious weed in many jurisdictions. Giant hogweed is native to the Caucasus Region and Central Asia. It was introduced to Britain as an ornamental in the 19th century, and it has also spread to Finland, Germany, France, Belgium, Czech Republic, Latvia, the United States and Canada.
The sap of giant hogweed causes phytophotodermatitis in humans, resulting in blisters, long-lasting scars, and—if it comes in contact with eyes—blindness. These serious reactions are due to the furocoumarin derivatives in the leaves, roots, stems, flowers, and seeds of the plant.
Woolston Eyes is a Site of Special Scientific Interest located in the town of Warrington, England, alongside the Manchester Ship Canal. The eyes themselves are used for the dumping of dredgings from the canal.
The Woolston Eyes Conservation Group manages the site as a nature reserve with access by permit only.
