This plant is one of the two yellow-flowered members of the Iris sibirica section, these plants have deeper yellow flowers than Iris forrestii, but with similar very narrow petals, and darking markings on the falls. They are robust, easy-to-grow plants and spectacular in flower
For best results, sow immediately onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. We sow most seeds in an unheated greenhouse and wait for natural germination, as many seeds have built-in dormancy mechanisms, often waiting for natural spring germination, hence giving them a full season of growth.
