Flowering Months

Iris pseudacorus bastardii is a particularly free flowering variety of our native Yellow Flag Iris. The creamy-yellow blooms are more subtle than those of Iris pseudacorus, and borne on branching stems from late spring. This hardy, moisture loving perennial is fast growing, and will quickly form a dense clump of greyish green, strap-like foliage, which makes a handsome addition to waterside planting schemes and bog gardens. Height: 120cm (48"). Spread: 30cm (12"). Planting depth: Zones 1, 2 & 3 to 20cm (8") 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 pseudacorus 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 pseudacorus in moist, boggy soils or submerged in the shallow margins of ponds with the crown to a maximum depth of up to 20cm (8") below water level. Choose a position in sun or semi shade.

More Info

When grown in damp borders, Iris pseudoacorus require 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 pseudoacorus 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.
