A beautiful long-lived clump forming perennial with lovely showy blue-grey flowers.
This campanula is a lovely addition to the garden, and is seldom found outside of specialist nurseries. It makes a compact mound of felted wavy edged grey green leaves. From this mound arises a stem up to 50cm high which bears many soft blue (sometimes white) flared flowers. It is sun and frost tolerant, can take partial shade, and is native to the Caucasus. It should be grown in very well drained soil. Rabbits do not eat it.
For best results, sow seeds 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. However, one can also sow most seeds in an unheated greenhouse and wait for natural germination as many seeds have built-in dormancy mechanisms, and often wait for spring before emerging regardless of when they are sown. But spring sowing will obviously give them a full season of growth if successful germination occurs.
