    Dendrobium wassellii requires very high light levels to get it to bloom.

    Thank you Ron, I did grow it under full sunlight recently. I always have a feeling that native orchids from southern hemisphere is hard to grow in the north. Don't know whether its's true or not?

    The southern hemisphere has such an incredible variety of conditions in which orchids grow that I'm sure you can find many species that will match your growing conditions. Ron is right about this one. It needs quite a bit of light to bloom.

    Thank you Wade. Besides Dendrobium wassellii , I have tried a few Laelia and Sophronitis ,Cattleya intermedia,Cattleya walkeriana and some Phragmipedium. But all are not successful. I am still working hard on the Cattleya intermedia and Cattleya walkeriana.

    Hi guys, a little late but managed to stumble upon this post.

    The genus has been changed to Dockrillia from Dendrobium, as this small genus lacks pseudobulbs. This species in particular is native to my state. It's found in the monsoonal hilly rainforest of far north Queensland (sub equatorial), where Summers are hot and extremely humid. Winters are warm and dry (often without any rain for 4-5 months at a time). Yes, it does require a LOT of light to flower. I'm further south and mine does well in full sun, no need to shade (at 27 degrees latitude) but is sensitive to frost.

    @silverhair, orchids don't care what hemisphere you grow them in provided the climatic requirements are met. I grow many northern hemisphere orchids here well with a little care to their requirements. Mine are a mixed bag, predominately cymbidiums as I'm in the coldest part of the state with many frosts, but my favourites are vandas, which I send down to my mother on the coast over Winter.

    If anyone is interested in native Australian orchids, I'm happy to offer advice based on my experience

    I have a fair number of "Aussie Dendrobiums" with Den. speciosum in them. Most are in 3" (7.5cm) pots. I don't think these are blooming size yet and I wonder if they need the cool and dry winter? Several of them are sending new growths at this time which I thought was strange considering we are in Fall here and temps are getting into the 40F - 50F (5C - 10C). I have them outside but plan to bring them in as soon as anything colder is predicted.

    Thank you for your info, Albinus. I'm still growing Dockrillia wassellii and wish them flower some day.

    Den. Speciosum is also known as the king orchid. Yes, that's a tiny plant. Many specimens here are in 1000mm (38") pots. They are rapid growers and are in full bloom here currently. They like full, but indirect sun (under a tree is good, mine are in gum trees), and there's a few cultivars ranging from yellow to pure white.

    A mature specimen will tolerate light frosts provided there's ability to grow during the warmer months. They have a perfume that is somewhat pleasant but can be overpowering when there's many flowering adjacently (such as at an orchid show). Here's my two:
