Cultivation Details
A plant of the tropics, where it is found at elevations from 600 - 2,800 metres. It grows best in areas where annual daytime temperatures are within the range 20 - 26°c, but can tolerate 16 - 35°c[1]. It prefers a mean annual rainfall in the range 750 - 2,000mm, but tolerates 600 - 2,400mm[1]. Requires a position in full sun[2]. Succeeds on most soil types, though it grows best in well-drained, humus-rich soils[2, 1]. Plants prefer a moist environment, though they are fairly drought tolerant once established[2]. Prefers a pH in the range 5.5 - 7, tolerating 5 - 7.5[1]. Plants can be coppiced[3]. Cultivated forms have been selected that are less bitter than the wild plant[2]. Flowering is induced by short days[2].
