Holder of the Royal Horticultural Society's prestigious Award of Garden Merit (AGM), this fabulous climber produces its dramatic, fragrant blooms from mid-summer to autumn. These are followed by greenish yellow to orange, egg-shaped fruit which is sweetly acid.

Hailing from the West Indies, Central and South America, it needs to be grown in a conservatory with a minimum temperature of 13C(55F) in the UK. Plant in the conservatory border or in a large container of John Innes No 3 soil-based compost. Water freely when in growth and top dress with fresh compost every spring.
