Growth
It is an 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.
I. 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.
Large I. pseudacorus stands in western Scotland form a very important feeding and breeding habitat for the endangered Corn Crake.
I. pseudacorus is one of two iris species native to the United Kingdom, the other being Iris foetidissima (Stinking iris).

Famous quotes containing the word growth:
“Every child has an inner timetable for growtha pattern unique to him. . . . Growth is not steady, forward, upward progression. It is instead a switchback trail; three steps forward, two back, one around the bushes, and a few simply standing, before another forward leap.”
—Dorothy Corkville Briggs (20th century)
“The risk for a woman who considers her helpless children her job is that the childrens growth toward self-sufficiency may be experienced as a refutation of the mothers indispensability, and she may unconsciously sabotage their growth as a result.”
—Letty Cottin Pogrebin (20th century)
“Cities force growth and make men talkative and entertaining, but they make them artificial. What possesses interest for us is the natural of each, his constitutional excellence. This is forever a surprise, engaging and lovely; we cannot be satiated with knowing it, and about it; and it is this which the conversation with Nature cherishes and guards.”
—Ralph Waldo Emerson (18031882)
