Cultivation Details

HabitAnnual
Growth—

A plant of subtropical to tropical areas. It is not very cold-hardy, tolerating temperatures down to about -5°c[2]. Plants can be grown outdoors in the temperate zone as half-hardy annuals, starting the seed off in a greenhouse. Prefers a rich light sandy soil[3] and an open sunny position[1]. It is best grown in a fertile calcareous soil[1]. This species is a commercial source of the alkaloid scopolamine, used in the pharmaceutical industry[4].

Propagation

Sow the seed in individual pots in early spring in a greenhouse[1]. Put 3 or 4 seeds in each pot and thin if necessary to the best plant. The seed usually germinates in 3 - 6 weeks at 15°c. Plant out in late spring or early summer, after the last expected frosts. Especially in areas with hot summers, it is worthwhile trying a sowing outdoors in situ in mid to late spring.
