hogweed

Also known as: cadweed; clogweed; cow parsnip; eltrot; giant parsnip; madnep; meadow parsnip

The hogweed is more diminutive than its infamous cousin, giant hogweed and doesn't carry the same health warnings. Although it may reach 2m in height, it's generally much shorter at 1m. Stems are ridged and hollow, leaves hairy with broad, pinnate lobes. Off-white umbels are borne from midsummer to early autumn. It may be a biennial or monocarpic perennial.
