CAMPANULA TRACHELIUM BLUE ENSIGN MIX
We have produced a superb mixture of the two forms of this lovely flower, and you will get, in roughly equal proportions, sizeable, flared, ivory-white or deep blue bells, which open along many strong stems carrying rough, jagged-edged, nettle-like (but non-stinging!) leaves. This tough, long-lived, clump-forming, non-running plant will only spread by seed, and is one of the essential cottage-garden plants of olden days.
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.
