A superb plant from the high Alps which is totally distinct from nearly all of the other 250 or so campanulas. It forms an attractive basal rosette of somewhat bristly, spatula-shaped leaves. From this eventually arises a thick, very leafy stem crowned by a glorious, very densely packed spike of fragrant creamy-yellow flowers.
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.
