Requires a rich well-drained soil and plenty of moisture in the growing season. Sometimes cultivated in China for its edible fruit and medicinal uses. Male plants are favoured for root production. This species is not winter hardy in Britain and usually requires greenhouse cultivation. However, it may be possible to grow it as an annual in a very warm sheltered bed outdoors. A climbing plant, supporting itself by means of tendrils. Dioecious, male and female plants must be grown if seed is required.
Seed – sow March in pots in a warm greenhouse in a rich soil. Sow 2 – 3 seeds per pot and thin to the strongest plant. Grow them on fast and plant out after the last expected frosts. Give some protection, such as a frame or cloche, until the plants are growing away well.
Fruit. The young fruits are pickled. The pulp of older fruits is eaten. Mature fruits are about 10cm long. Leaves and young shoots – cooked and used as a vegetable. An edible starch is obtained from the root. It requires leeching, which probably means that it has a bitter flavour. The root is harvested in the autumn, cut into thick slices, soaked for 4 – 5 days in water, changing the water daily until the root disintegrates and can be mashed into a fine pulp. It is then steamed into cakes or used for making dumplings. An edible oil is obtained from the seed.
Chemical components: The plant is a source of the toxic anti-HIV type I ribosome-inactiving lectin trichosanthin
