A striking rush with its sturdy rounded stems, hollow within, and marking their length with regularly set dark brown nodules that band the stem as though it were a measuring stick. It does not have leaves. This is a vigorous plant that will happily invade available territory if there is sufficient moisture for its needs. Historically this was used as scouring material. Give it a sunny or part shaded site in water or any very moist site. it stands up to 1.5m (5ft) high with a 2m (7ft) spread.
This has strap-like, mid-green leaves that can go well over 1m (3ft) high in watery conditions and yellow blossoms with black markings. It is a familiar plant of river and marsh throughout Britain and Ireland. This may be the original fleur-de-lis, although it is not certain whether the heraldic fleur de luce, used by Louis VII as his blazon at the time of the Crusades was derived from the iris or the lily. There are a number of cultivars.
This is a pretty rush that has slender, bright green foliage that is arching and weeping in its habit. It produces small brownish flowering spikes that make dots amongst the foliage. This is often grown as a houseplant in a container. It is equally at home in the garden, and is especially suited to a position alongside water. It's not hardy throughout the country and requires damp soil, enjoying acidic conditions.
This Iris can be vigorous in boggy soil. It is the original of the famous Royal French emblem, Fleur-de-lys.
After foliage has died back in Autumn cut back to just above the water surface. If trimming left until spring take care not to damage emerging shoots.
