Our beloved and familiar native flag iris. An easy plant to grow, with the typical long mid-green iris leaves and yellow flowers in late spring to early summer which are attractive to bees. When allowed plenty of room it is a large plant, but to a certain extent it can be contained for smaller ponds by dividing and re-potting once a year. It will grow in shady positions (here in Norfolk it is widely seen growing in the shadowy light of woodland streams) but requires a sunny position in order to flower well.

Gardeners have developed a number of cultivars of this species over the years; there is a smaller version, a variegated version, a white version, and a double-flowered version.

Please note that all irises may cause skin irritation and are somewhat poisonous if eaten.

If designing a planting scheme, we recommend approximately 1 Iris pseudacorus plant per square foot of ground or per linear foot of pond edge. Read more here on how to pot and care for your plant.
