Iris pseudacorus ‘Alba’ is a less vigorous variety than the native Yellow flag the Iris pseudacorus. ‘Alba’ has broad green sword-shaped leaves and large creamy-white flowers with a pale yellow signal edged in charcoal grey. Flowers during May and June. Propagate by division in Spring or Autumn or by seed collected from the seed pods in Autumn. Good for bees and hoverflies looking for nectar. The tall leaves are valuable for dragonfly larvae climbing out of the water to pupate and the dense leaves give good coverage for frogs and toads and also visiting birds. As with all irises the rhizomes are harmful if eaten.
Height: Up to 1m
Planting position: Pond marginal shelf up to 20cm deep or very wet soil
