These are the beautiful sweet smelling Ginger. Hedychium gardnerianum from North India is perhaps the best known. It grows to a height of 2 m (6 ft) planted into the greenhouse border but a little shorter in a pot. Flowers are a showy yellow with bright red stamens. H. greenei is a little shorter and the flowers an orange-red. H. coccineum has up to 50-cm (20-in) long leaves and red flowers. These plants are almost herbaceous although sometimes their foliage does not completely die down before new shoots emerge from the rhizome. If grown in pots they should be allowed to rest a little during winter although not letting them dry out completely. They are better kept at a minimum of 10°C (50°F) although they can tolerate cool conditions. They should be repotted every other year in spring when division of the rhizomes can also take place. Seeds can be sown in spring after being soaked for two hours and will take three weeks to germinate at 21-24°C (70-75°F).
