Growth—

A plant of the warm tropical lowlands with low to high rainfall[1]. It grows best in areas where annual daytime temperatures are within the range 18 - 28°c, but can tolerate 12 - 34°c[2]. It succeeds with a mean annual rainfall in the range 300 - 3,500mm[2]. Often an epiphytic plant, though it also grows on the ground. Requires a well-drained soil and a pH of 6 or lower[3]. Prefers a pH in the range 5.3 - 6.7, tolerating 5 - 7.5[2]. Plants grow well, but do not always set fruit well, when growing in the wetter areas of the tropics[4]. The fragrant flowers open during the night[5].
