Campanula is the largest genus in the bellflower family, Campanulaceae, with over 500 species spread across the northern hemisphere, most around the Mediterranean across to the Caucasus. The species are very diverse from prostrate high alpines, to tall meadow and woodland plants. Two species, Campanula rotundifolia and Campanula uniflora are native to Iceland (*).
A stalk without buds is torn off at the base and planted in soil mixed with pumice and kept in a sheltered spot out of strong sunlight until the cutting is rooted.
Seed - sown in January
Seed just covered and kept at 20°C (68°F) until germination. Germination can be slow and take 3 months. After germination it should be kept at a lower temperature with plenty of light so the plants won't become lanky. The seed can also be placed in the refrigerator for 8 weeks and then stored at 20°C (68°F) until germination.
Has a trailing habit that is best suited to rock gardens and walls.
