Audas’ spider orchid

Audas' spider orchid is a rare, deciduous ground orchid native to Victoria, Australia, growing from an underground tuber with a single hairy leaf and one yellow flower in spring. It is a wild species of conservation concern and is not commonly grown in home gardens, so care depends on mimicking its native grassy woodland.
