Cardamine flexuosa
Ecology
A winter- or summer-annual, or rarely a short-lived perennial, most frequent in open, moist, shaded vegetation in marshland, by rivers and streams, and in gardens. It prefers soils which are at least mildly basic, and is absent from those that are strongly acidic. It is an effective colonist of disturbed, fertile habitats. Generally lowland, but reaching 830 m on Snowdon (Caerns.) and 1190 m in the Breadalbanes (Mid Perth).
