Flowers open like dazzling butterflies, in the brightest red you can get, crowding two foot stems for a very long time in mid-summer. Although it will grow in any good soil, it is a superb plant for boggy or even wet conditions and in the margins of a pond it makes a stupendous sight.
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.
