Frosted Hogweed
Hogweed is a biennial, or monocarpic to polycarpic perennial native in grassy places, along hedges, on rough ground, roadsides and banks. It may show a preference for chalk soils. Hogweed is chiefly a problem on pasture but may encroach onto arable land from the hedgerow or headland. However, although common in the hedge bottom it is rarely found further than m into the arable field. In a survey of weeds in conventional cereals in central southern England in 1982, hogweed was found in 2, 3 and 1% of winter wheat, winter barley and spring barley fields respectively. It can be a weed of perennial crops such as fruit. Hogweed is a variable species and 9 geographical variants have been recognised. Two of the nine subspecies occur in Britain. Subspecies sphondylium is widespread but ssp. sibiricum occurs only in parts of East Anglia and may have been introduced. Hybrids occur between the common hogweed and the giant hogweed (H. mantegazzianum).
