Intense blue flowers up to ¾in, produced in great profusion and in an endless procession from late spring to frosts. Its habit of producing a large number of base stems gives a neat, compact form of bedding. However, the stems are suitably springy and become pendulous in hanging baskets and other containers.

Sow from January to early April in a good free draining compost. Surface sow and cover preferably with a thin layer of vermiculite or 1/16in of compost. Germination usually takes 18-21 days at 65-70F (18-20C). As soon as seedlings start to emerge, lower the temperature to 60F (15C). Germination can sometimes be slow and erratic, don't discard the container too early as a second flush of seedlings may appear later.

Transplant seedlings when large enough to handle into 7.5cm (3in) pots. Harden off and plant out, when all risk of frost has passed, 23-30cm (9-12in) apart in full sun.

Prefers a well drained soil. When planting in hanging baskets or container take care not to overwater in early stages. They also make attractive pot plants for winter flowering under glass.
