Trichosanthes dioica


Trichosanthes dioica, also known as pointed gourd, is a vine plant in the family Cucurbitaceae, similar to cucumber and squash, though unlike those it is perennial. It is a dioecious vine plant with heart-shaped leaves and is grown on a trellis. The fruits are green with white or no stripes. Size can vary from small and round to thick and long — 2 to 6 inches. It thrives well under a hot to moderately warm and humid climate. The plant remains dormant during the winter season and prefers a fertile, well-drained sandy loam soil due to its susceptibility to water-logging.
