This astonishingly tough rockery plant bears in spring and summer sprays of violet starry flowers. Vigorous and fast growing, it is one of the easiest and long-flowering of all rockery plants, and able to stand almost complete drying out once established in a wall.
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.
