Leptoceras spp.
rabbit orchid
Overview
Leptoceras spp. is a genus in the orchid family (Orchidaceae) with a single species, Leptoceras menziesii, the rabbit orchid, endemic to south-western Australia. It is a small terrestrial orchid growing from an underground tuber, producing a single broad leaf that lies near the ground, sometimes flushed red. The slender flowering stem reaches 10-30 cm (4-12 in) and carries one to four flowers, each white to pink with red markings and two narrow, erect petals held upright like a pair of ears, the feature behind the common name. Flowering occurs in spring and is often more profuse in the season after a summer bushfire. The flowers are pollinated by native bees and other insects. The orchid grows in sandy and gravelly soils in heath, shrubland, and open woodland, and relies on symbiotic soil fungi to germinate and grow. As with most Australian terrestrial orchids, the plant is dormant as a tuber through the dry summer and reappears with autumn and winter rain. It is challenging to cultivate because of its fungal dependence and specific seasonal needs.
Native Range
Leptoceras menziesii is endemic to south-western Australia, where it grows in sandy or gravelly soils in heath, shrubland, and open woodland. It is widespread within that region.Suggested Uses
Grown by orchid specialists and in conservation collections rather than general gardens. In the wild it forms part of the ground flora of heath and woodland and has little use in conventional landscaping.How to Identify

Care & Maintenance
Care Guide
This orchid is rarely cultivated and challenging outside its native range. It requires sandy, sharply drained acidic soil, a symbiotic root fungus, and a seasonal cycle of winter growth and summer dormancy. Watering matches the natural rhythm, moist in the cool months and dry in summer. Soil disturbance or loss of the fungal partner leads to decline. It is grown mainly by specialist terrestrial-orchid enthusiasts in deep pots rather than open gardens.Pruning
No pruning is applicable. The leaf and flowering stem wither as the plant enters summer dormancy as a tuber. Spent growth is left undisturbed.Container Growing
