Hedychium stenopetalum

Germination

Sow seeds indoors as soon as possible. Prior to sowing soak seed for 2 hours in warm water. If seed swells sow immediately, if not prick the seed gently with a pin and soak again. Sow 1-2mm deep into moist, well-drained seed compost. Place in a propagator. Ideal temp. 21-25°C. Keep moist and in bright light. Germination takes 20-25 days approx. Transplant seedlings when large enough to handle to 8cm pots and grow on. If planting out acclimatise for 10-15 days after danger of frost has passed.

Growing

Grow under glass in the UK in a loam-based compost in bright, indirect light. Outdoors prefers a humus-rich, moist but well-drained soil in full or partial sun. Best container grown where it can be moved outside in warmer weather and taken in to offer protection during cold spells. Shelter from cold winds and offer a deep winter mulch as protection from frost. Water and feed well when in full growth. If allowing to die back for winter cease feeding by august.

Cultivation

Cut back foliage and old flower spikes at the end of the growing season. Propagate by fresh seed or by division of rhizomes in spring.
