When large enough to handle, transplant the seedlings to 7.5cm (3in) pots and over-winter in a cool greenhouse, conservatory or on a well lit windowsill with a temperature of around 7C (45F). Plant out the following spring 1m (3ft) apart, into a sunny site with well drained soil.
Although this species is proving to be quite cold hardy, its best to cover the base of the plants with a little bracken or similar over the winter. They can also be grown in 30cm (12in) pots to flower in a conservatory or cool greenhouse.
