The flowers are perhaps the most powerfully scented of all flowers. The perfume is almost intoxicating, especially when the plant is grown in gentle heat when it is heavy and sickly almost to the point of unpleasantness[
]. A double-flowered cultivar, 'The Pearl' has an even more pronounced fragrance[
Flowers - cooked. Used in vegetable soups or added to the substrate of 'kecap', an Indonesian soy sauce[
The flowers are the source of tuberosa-flower water[
]. No further details are given.
An essential oil is obtained from the flowers. It is used in high grade perfumery[
]. 1150kg of flowers yield 1kg absolute essential oil[
Seed - we have no information on this species but suggest sowing the seed in spring in a sunny position in a greenhouse. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
Division of offsets after the plant has finished flowering in late summer.
