Flowering Months
This moisture loving Blue Flag makes a handsome addition to boggy areas and the shallow margins of ponds. Over time, Iris versicolor will form dense clumps of narrow, strappy foliage that provide good cover for wildlife at the water’s edge. In early summer, each of the stiff flowers stems is topped with up to five blue Iris flowers with distinctive purple-veined falls. This resilient hardy perennial is at its best when planted in large drifts as a marginal aquatic. Height: 90cm (36"). Spread: 30cm (12"). Planting depth: Zones 1 & 2 to 15cm (6") below water level.

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

How to Grow
Iris versicolor plants thrive in damp, acid or neutral soil in a sunny or semi-shaded position. These moisture loving Iris require a rich, fertile soil which has had plenty of well rotted organic matter added into the soil prior to planting. Grow Iris versicolor in moist, boggy soils or submerged in the shallow margins of ponds with the crown to a maximum depth of up to 15cm (6") below water level. Choose a position in sun or semi shade.
More Info
When grown in damp borders, Iris versicolor requires reliably moist soil. Water if necessary during dry periods to prevent the soil from drying out. Overcrowded clumps of Iris plants can be divided in autumn after flowering. Mulch around the base of Iris velsicolor in spring to help retain moisture at their roots. Iris that are grown in ponds may be cut back to just above the water surface in autumn.
