Red Hemp-nettle

An annual of arable land, waste places and open ground on calcareous substrates, including limestone pavements and scree; also found on eskers and on coastal sand and shingle. This late-flowering species often fails to set seed within winter-sown crops. 0-320 m (Derbys.).

Bifid Hemp-nettle

An annual of arable, waste and cultivated ground, and less often woodland clearings and ditch-sides. It is found in similar places to G. tetrahit, and often grows with it, although more strictly an arable weed. Lowland.

Downy Hemp-nettle

An annual weed of arable and waste ground, most frequently found as a casual in root-crops. Lowland.

Large-flowered Hemp-nettle

An annual weed of cultivated, marginal and waste ground, often within root-crops (especially potatoes) on peaty soils. 0-445 m (Clun Forest, Salop).

Common Hemp-nettle

An annual of habitats such as woodland clearings, ditches, fens, river banks, roadside verges and wet heaths, but perhaps more frequent in disturbed arable, waste and cultivated ground. 0?450 m (Clun Forest, Salop).

Common Hemp-nettles

These annuals grow in moist, moderately shaded semi-natural habitats such as woodland clearings, ditches, fens, river banks, roadside verges and wet heaths, but perhaps more frequently in disturbed arable, waste and cultivated ground. 0?445 m (Clun Forest, Salop).
