Yellow Iris pseudacorus Giant is a bold, vigorous pond marginal that produces masses of vivid yellow flowers in spring, making it one of the most eye-catching plants at the water's edge. A giant form of the classic Yellow Flag Iris, this variety grows taller and fuller than the standard type, with broad, sword-shaped foliage that provides excellent vertical structure throughout the season. It thrives in shallow water or boggy soil at depths of up to 30cm and is extremely hardy. A great choice for naturalising pond margins and providing habitat for wildlife.
