Enormous hairy basal leaves form a base for an immense display of white-tongued vivid purple-blue flowers on long, strong branching stems. This spectacular plant is bone hardy, long-lived and makes a stupendous display all summer long!
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.
