Description

Iris pseudacorus (yellow flag, yellow iris, water flag) is native to Europe, western Asia and northwest Africa.

It is an herbaceous flowering perennial plant, growing to 100–150 centimetres (39–59 in) (or a rare 2 metres (6 ft 7 in)) tall, with erect leaves up to 90 centimetres (35 in) long and 3 centimetres (1.2 in) broad. The flowers are bright yellow, 7–10 centimetres (2.8–3.9 in) across, with the typical iris form. Iris pseudacorus grows best in very wet conditions, and is often common in wetlands, where it tolerates submersion, low pH, and anoxic soils. While it is often grown as an aquatic plant, the rhizomes can survive prolonged dry conditions, and can be grown in regular garden soil.

The plant was rated in second place for per day nectar production per flower in a UK plants survey conducted by the AgriLand project which is supported by the UK Insect Pollinators Initiative. Large I. pseudacorus stands in western Scotland form a very important feeding and breeding habitat for the endangered corn crake.

This variegated cultivar has gained the Royal Horticultural Society's Award of Garden Merit.

Seeds per pack: 5 Large seeds

Note: Ornamental use only. These seeds and/or plants are poisonous.

Germination: Start these seeds right away for best germination rates. Your planting container should have holes in the bottom for excess water to drain. Sow the seeds just under the surface of a sterile seed-start mix, and water in. Leave them at room temperature for 5 weeks. This helps break the phytohormones which inhibit germination. They will not grow yet. Then a cooling period is required. Cover them with plastic and place in a fridge for 80 days. Be sure they stay moist. After the cold-moist stratification period they are then brought back to a cool room (15C, 59F) for them to germinate. Germination is generally 30-90 days after the warming period, though some can take longer.
