Gynostemma pentaphyllum (common name: sweet tea vine)

Propagation: Pre-soak the seed for 24 hours in warm water and then sow it in spring in a rich compost in a greenhouse, placing 2 - 3 seeds per pot. Thin the seedlings to the strongest in each pot and grow the plants on fast. Plant them out after the last expected frosts and protect them with a frame or cloche until they are growing away well.

Cultivation: Requires a rich well-drained but moisture-retentive soil in a warm sheltered position in partial shade[1].

This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c[2]. A problematic crop outdoors in Britain, it can be grown successfully as an annual in a greenhouse but requires a long hot summer if it is to do well outdoors.

Plants tend to be annuals or short-lived perennials[1].

A climbing plant, attaching itself to supports by means of tendrils[1].

Dioecious, male and female plants must be grown if seed is required. Some plants might be monoecious[2].

The leaves have a sweet taste and are used as a tea[5][6][7].

Medicinal: The whole plant is a tonic herb that improves the circulation, stimulates liver function, strengthens the immune and nervous systems, and reduces blood sugar and cholesterol levels[1]. It also has sedative effects, relieving spasms and lowering the blood pressure[1]. It is used internally in the treatment of nervous tension and exhaustion, peptic ulcer, asthma, bronchitis, diabetes, cardiovascular disease and cancer[1]. It was rated among the ten most important tonic herbs at a conference on traditional medicines in Beijing in 1991[1].
