A fast growing and exotic-looking climber, with large deep purple flowers from July to October.  The flowers are bell-shaped with an attractive fragrance.  Plants have tendrils which help them climb up walls and trellises, to a height of about 4m.  Plants grow quickly and sowings in early spring flower the same year and cover a large area.  RHS Award of Garden Merit.

Cobaea grows best in a sheltered place with full sun a south or west facing wall or trellis is ideal.  Soil should be moist and well drained.   Plants will grow well in big pots with plenty of water.  These are perennials and will survive many years if protected from frost they make good conservatory plants and will flower into early winter in a sunny conservatory.
