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.
