Iris pseudacorus 'Variegata'

This is a handsome form of our native yellow flag, which grows in marshy ground or shallow water. It will also grow in rich, retentive soil. In early spring the newly emerging fans of leaves are pale butter-yellow (Image 2). This remains for several weeks, deepening as the leaves mature, until by June they are green. Yellow flowers have distinct brown markings. Harmful if eaten.
