Propagation

This section contains historical Plants For A Future notes marked noncommercial.

Seed - sow early spring in a warm greenhouse. Germination is usually fairly rapid. Prick out the seedlings into individual pots when they are large enough to handle. If growing them as annuals, plant them out into their permanent positions in early summer and protect them with a frame or cloche until they are growing away well. If hoping to grow them as perennials, then it is better to grow them on in the greenhouse for their first year and to plant them out in early summer of the following year. Cuttings of half-ripe wood, July/August in a frame. Overwinter them in a warm greenhouse and plant out after the last expected frosts.

Cultivation

This section contains historical Plants For A Future notes marked noncommercial.

Prefers a well-drained humus rich fertile soil in a sheltered position in full sun[5]. A very ornamental plant[1], it is an annual or short-lived perennial. Not very frost-tolerant, if started off early in a warm greenhouse it can be grown as an annual in Britain, flowering and setting seed in its first year.
