Iris pseudacorus (yellow flag, yellow iris, water flag) is a species in the genus Iris, of the family Iridaceae. It is native to Europe, western Asia and northwest Africa. Its specific epithet, meaning "false acorus," refers to the similarity of its leaves to those of Acorus calamus, as they have a prominently veined mid-rib and sword-like shape.
It is a herbaceous flowering perennial plant, growing to 1-1.5 m (or a rare 2 m) tall, with erect leaves up to 90 cm long and 3 cm broad. The flowers are bright yellow, 7-10 cm across, with the typical iris form. The fruit is a dry capsule 4-7 cm long, containing numerous pale brown seeds. Iris pseudacorus grows best in very wet conditions, and is often common in wetlands, where it tolerates submersion, low pH, and anoxic soils. The plant spreads quickly, by both rhizome and water-dispersed seed. It fills a similar niche to that of Typha and often grows with it, though usually in shallower water. While it is primarily an aquatic plant, the rhizomes can survive prolonged dry conditions.

FFF 34 - DUTCH IRIS
Iris is a genus of 260-300 species of flowering plants with showy flowers. It takes its name from the Greek word for a rainbow, referring to the wide variety of flower colours found among the many species. As well as being the scientific name, iris is also very widely used as a common name for all Iris species, though some plants called thus belong to other closely related genera. A common name for some species is 'flags', while the plants of the subgenus Scorpiris are widely known as 'junos', particularly in horticulture. Irises are popular garden flowers.

The showy graceful blooms of Dutch Iris (Iris xiphium - also called Spanish Iris!) provide height and colour in mid- to late spring. Definitely one of the easiest and most reliable spring bulbs to grow, they perform well in both open sunny positions as well as in part or full shade.
Flower colour varies from white and yellows through to many shades of blue and purple in either single colour standards and falls through to a combination of both. They are very frost hardy and prefer a sunny position with ample moisture during growth, but none during their dormancy in summer. They can be grown in pots and terrace planters and are ideal as cut flowers for vases and arrangements. Dutch Iris grow to a height of 40 to 50cm.

FFF15 - THE GODDESS OF THE RAINBOW
Iris is a genus of about 300 species of flowering plants with showy flowers. It takes its name from the ancient Greek goddess of the rainbow, Iris, referring to the wide variety of flower colours found among the many species. As well as being the scientific name, iris is also very widely used as a common name for all Iris species, though some plants called thus belong to other closely related genera. A common name for some species is 'flags', while the plants of the subgenus Scorpiris are widely known as 'junos', particularly in horticulture. It is a popular garden flower and its blossoms provide wonderful splashes of colour in the Spring garden.
The genus is widely distributed throughout the north temperate zone. Their habitats are varied, ranging from cold and montane regions to the grassy slopes, meadowlands and riverbanks of Europe, the Middle East and northern Africa, Asia and across North America. Irises are perennial herbs, growing from creeping rhizomes (rhizomatous irises) or, in drier climates, from bulbs (bulbous irises). They have long, erect flowering stems which may be simple or branched, solid or hollow, and flattened or have a circular cross-section. The rhizomatous species usually have 3–10 basal sword-shaped leaves growing in dense clumps. The bulbous species have cylindrical, basal leaves.
