The "Yellow Flag" is one of our worthwhile-to-grow native wild irises. Large bright yellow flowers flare open in spring amidst stiff green leaves. Supposedly a bog plant, but it also thrives on our dust-dry hillside!
Sow immediately at any time onto preferably a soil-based compost, covering with fine grit to approximately their own depth. Germination MAY be quicker if kept at 15 to 20 degrees C. but many seeds WILL NOT come up the year they are sown, needing winter chilling after sowing, and ONLY come up with natural spring germination.
