Iris pseudacorus bastardii

Iris pseudacorus 'Bastardii', commonly known as Bastard Flag iris, is a tall, clump-forming aquatic perennial with upright, sword-shaped green leaves that create strong vertical interest at pond edges or in wetland gardens. In late spring it produces large, pale yellow flowers above the foliage, forming a striking display that stands out in damp borders and naturalistic water features.

This cultivar thrives in consistently wet or shallowly submerged soil and provides ecological value by supporting pollinators such as bees. Its vigorous growth habit and tolerance of waterlogged conditions make it ideal for pond margins, marshy areas, and wetland plantings where moisture is reliable.
