Diuris orientis – Wallflower Orchids or Bulldog
This is a very common donkey orchid, which is always a pleasure to find on a plesant spring day.
It would have to be one of the most striking, , spring flowering orchids. In a field of flowers they are quite spectacular, and will often be found with other spring flowering orchids including Diuris pardina (which it commonly hybridizes with), Glossodia major, and Thelymitra sp. It flowers from September to November, and is found from Western Australia, right across the southern region of Australia to Victoria and Tasmania.
This orchid has been observed to grow in a variety of habitats and soil types. It will regularly form colonies which can be very spectacular.
There is a yellow variety of this orchid. In South Australia this variation is not particularly common. Contrastingly in the eastern states, they mainly have the yellow variety and less of the colourful variety that we have here. Personally I like the colourful one better. There is reasonable variety between the flowers with some have a deep maroon to vivid purple and sometimes white on the labellum.
