FFF56 - YELLOW FLAG

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.

  2. And we also have it here, in fact it is one of the plants at the building grounds below. But it easily gets ugly with a not so fertile soil, and succumb to pests.
