Germination will occur the following spring. Seed may also be started indoors during the latter part of the winter so that seedlings will be large enough to be hardened off in the early spring. From Cuttings Basal cuttings can be taken in the spring from most species while to increase the number of smaller species it is best to take cuttings from the new, early summer growth. It has become very popular during the last ten years or so, and I frequently see it these days in area gardens. It is native to central Europe.
Colour can be variable.
Most commonly it is a delightful blue but can be blue-purple or white. Flowers are borne profusely and each about 3 centimetres across. Individual plants grow to about 25 centimetres in height and can attain a spread of up to 60 centimetres. It tolerates a wide range of conditions, and is capable of spreading quickly. It can be used in a rock garden but it is equally at home in a raised bed or near the front of a herbaceous bed or border.
