Lyperanthus is a small genus of 4 species, all of which occur only in Australia.
Lyperanthus suaveolens has a single, linear leaf up to 20 cm long. Flower stems are up to 45 cm tall bearing between 2 and 8 greenish-yellow to brown flowers each about 30mm diameter. Flowering occurs in spring and the plants become dormant in summer when they die back to an underground tuber. The flowers have a strong perfume which is particularly noticeable on warm days.
Although L.suaveolens is a little easier to grow than many other terrestrial orchids, it is cultivated mainly by orchid enthusiasts. Generally the plants are grown in pots in a freely draining, sandy mix. They require good air circulation in a protected position of about 50% sun during the growing period from late summer. During this growing period the plants must not be allowed to dry out. After the leaves have died back to the tuber, the pots are allowed to dry out completely.

Propagation of orchids requires specialised methods and is rarely attempted by the casual grower. The following references provide further information on growing terrestrial orchids from seed.
