A rather robust, conspicuous and persistent perennial herb, widely if sparsely established from garden outcasts on road- and lane-sides and by woodland margins, but seldom far from habitation. Lowland.
I. helenium has been grown in gardens for its medicinal and ornamental value since at least 995 (Harvey, 1981). It is very persistent but it may be in gradual decline.
Native of W. & C. Asia; widely naturalised in temperate Europe and elsewhere.
