A very popular orchid grown in culture in South Australia is the epiphytic/lithophytic Dendrobium speciosum. It is a showy species with a heady perfume.
This species ranges along the eastern seaboard from Queensland just peeking into Victoria. There are nine variations each with its own unique distribution.
But not only is it popular in South Australia, it is popular throughout the country. The whole of the 2006 September issue of the Orchadian was devoted to a single article on D. speciosum. The March 2016 Orchadian has three articles plus references to D. speciosum in other articles.
And then there is Gerry Walsh who is so passionate about this species that he has a comprehensive website – The Rock Lily Man – devoted to it. Explore and enjoy his website.
The Orchid Club of South Australia has produced a fact sheet for growing this species in South Australia.
