Propagation

Seed - sow early spring in a greenhouse and only just cover the seed. Germination usually takes place within 2 - 25 days at 20°c. When they are large enough to handle, prick the seedlings out into individual pots and plant them out after the last expected frosts.

Cuttings of half-ripe wood, 5 - 7cm with a heel, July/August in a frame[7]. High percentage. Because the plant is not hardy the cuttings would have to be grown in a greenhouse for the winter before planting them out in the spring.

Cuttings of young shoots in the spring[8]. Because the plant is not hardy the cuttings would have to be grown in a greenhouse for the winter before planting them out in the spring.

Cultivation

Prefers a rich well-drained soil in full sun[5]. Plants grow best in a sandy loam[9].

Severely damaged by low temperatures[8], this plant is not hardy in Britain but it can be grown as a half-hardy annual, flowering in its first year from seed[8][5]. If grown as a shrub, it requires a minimum winter temperature of 5 - 7°c[5]. Plants stop growing when night-time temperatures fall below 5°c and are likely to be killed once the temperature falls below -2°c[9]. The plant turns its leaves and flowers so that it is always facing the sun during the day[6]. The flowers have a most unusual perfume, somewhat like cherries baked in a pie[4]. It is a good butterfly plant[10][11].

A parent of the cultivated ornamental garden heliotropes[8], there are many named varieties[5].
