This new plant carries flat heads of deepest purple daisies flowering on strong stems in September and October. Valuable late colour when almost everything else in the garden has died away. Associates well with late cimicifugas and aconitums.
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.
