After flowering the plant and its tuber die back and to provide food for the production of a fresh tuber and shoot. As the plant produces young plants vegetatively, propagation may be done simply by division. Established plants are divided after flowering. Wash the growing medium from the roots and carefully separate the young plants before repotting. Another method of propagation is from seed.
Fresh seed is sown on washed Irish peat or sphagnum moss.
Fill the pot with a layer of coarse, washed river sand and place a layer of peat or sphagnum over it. Sow the seed evenly and lightly spray the entire surface with a suitable fungicide, e.g. Kaptan. Cover the pot with clear plastic, held firmly in place with an elastic band or use a pane of glass. Place in a shady position and germination will take place after four weeks. Keep medium moist, by placing the pot in a tray of water.
