IRIS LAEVIGATA 'COLCHESTERENSIS'
This superb form of Iris laevigata which was selected here and comes pleasingly true from seed, has gorgeous, sumptuous white flowers, heavily painted in deepest navy blue. It is fine in the ordinary garden but outstanding in damp or wet soil.
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.
