Iris pseudacorus ‘Variegata’ (Variegated Yellow Flag Iris) is a striking ornamental iris grown primarily for its bold foliage. It features upright, sword-shaped leaves with attractive green blades striped with creamy yellow, providing season-long interest even when not in bloom. In late spring to early summer, it produces bright yellow iris flowers on tall stems above the foliage. This vigorous perennial is commonly used near water features, pond edges, and in moist landscape areas where its strong growth habit can be managed.
