Ecology

A biennial herb of open scrub and hedge banks, waysides, railway banks and sidings, rough grassy places, waste ground and quarries. It prefers well-drained soils, especially those over a sand, gravel or chalk substrate. It produces copious long-lived seed and may become an abundant colonist. It is a frequent garden escape, becoming established on rubbish tips when thrown out. 0-370 m (White Scars, Ingleborough, Mid-W. Yorks.).
