A showy climber for the cool greenhouse, conservatory, and also forming a very decorative screen on trellis or south facing wall in milder areas. The large bell shaped 'cup and saucer' flowers are often 6cm (2½ in) across. Flowers late summer. Climber.
Soak the seed for 2 hours in lukewarm water before sowing. Sow late winter to early spring at 18-24C (65-75F) in a good seed compost. Sow the seeds on their edge and just cover with compost. Keep soil damp but not wet, sealing in a polythene bag after sowing is helpful. Germination usually takes 21-30 days.
