Prasophyllum triangulare
Dark leek orchid is a tall terrestrial orchid from south-west Western Australia, grown from a tuber and flowering only after fire the previous summer. It is a wild native rather than a common garden plant, so it is best left in its natural habitat or cultivated only with specialist care.
