Cultivation Details

HabitAnnual/Perennial
Growth—

Plants succeed in the tropics and subtropics[1]. Prefers a deep, well-drained, moderately fertile sandy loam and a position in full sun[1]. Originally native to the tropical Americas, this plant has escaped from cultivation and become naturalized in many other areas in the tropics. The plant has a strong, unpleasant smell[2]. The plant is an alternative host of Alternaria cassiae, which affects crops such as cowpea (Vigna unguiculata) and several Solanum species[3]. There are conflicting reports on whether or not this tree has a symbiotic relationship with certain soil bacteria, so it is unclear as to whether this tree fixes atmospheric nitrogen[4].

Propagation

Seed - scarify and then pre-soak the seed for 2 - 3 hours in warm water before sowing it from early spring to early summer in a warm greenhouse[5]. The seed usually germinates in 1 - 12 weeks at 23°c[5]. Prick out the seedlings into individual pots once they are large enough to handle and grow them on in the greenhouse. Do not plant them out until the following spring[5]. Division as growth commences in spring[6]. Cuttings of moderately ripe wood, July in a frame[7].
