Ecology

An annual of cultivated ground, manure heaps, roadsides, rubbish tips and waste places in towns and cities; also on fertile soils in a wide range of disturbed semi-natural habitats, such as river banks, pond margins and sea-bird cliffs. A. patula is frequent in coastal waste places but rare in littoral zone habitats such as saltmarshes and sand and shingle drift-lines. Mainly lowland, but reaching 435 m in Clun Forest (Salop).
