An easy to grow exotic climber, with lily-like flowers in a wide range of vibrant colours. Ideal for creating a spectacular feature plant climbing up an obelisk in containers or through trellis in borders.
Climber 180cm (6ft).
Sow February to April. Sow seeds into pots or trays of moist seed compost and cover with a sprinkling of compost or vermiculite. Place in a propagator or warm place, and keep at a temperature of around 20-30C (68-86F). After sowing, do not exclude light as this helps germination. Keep the surface of the compost moist but not waterlogged; germination will usually take 30-40 days.
When large enough to handle, transplant seedlings into 7.5cm (3in) pots of good quality , soil-less compost and provide support for climbing shoots.
In the autumn , gradually dry off tubers and store loose , in a cool, dry and frost free place over the winter. Re-pot in early spring into 13cm (5in) pots and grow on as before, re-potting further as necessary. Grow on in a greenhouse or conservatory.
Water freely during the growing season . Tubers can take 2-3 years to flower.
Tubers are highly poisonous.
