To make the most of the growing season Cobaea scandens seeds are sown in February or March. Before sowing soak the seed for 2 hours in lukewarm water before sowing. To maintain the temperature place the seeds and water inside a thermos flask.
Using a modular seed tray, fill with a good quality peat-based compost and gently water in. Allow the excess water to drain off and then press one seed into the surface of the compost at a rate of one seed per module. Do not cover the seed as it requires the presence of light to help initiate germination.
Place the tray inside a heated propagator at a temperature of between 18-24C and place on a warm bright windowsill, but out of direct sunlight during the warmest part of the day. Alternatively seal inside a clear polythene bag after sowing is helpful. You can expect germination to occur within 21-30 days.

after all risk of frost 60cm (24in) apart in a sheltered spot in sun on ordinary well drained soil. For summer flowering under glass, transplant into 20-23cm (8-9in) pots, and keep the atmosphere fairly humid.
The 'Cup and Saucer' plant will do best in a sunny, sheltered position in ordinary well-drained soil. Avoid the temptation of adding fertilizer to the soil beforehand as this can reduce the number of blooms.
