    Can someone provide me with some real-life experience with this plant, please? It's growing okay for me, but I'm curious what I need to do to make it bloom.

    TIA!

    It needs a dry rest. I'll post more this evening when I have time.

    Here's the plant I purchased as "den jonesii". I don't think it is, based on Marni's plant shot and description.

    I don't remember mine ever looking like that. It has that speciosum look. I looked up D jonesii in Baker and it states that it is considered by some as a part of D speciosum alliance. It is in the Dendrocoryne section which includes tetragonum, kingianum, fleckeri. The Mr. Bill book has it as a valid species with synonyms of fusiforme & ruppianum (the name mine had originally). Most everyhing in that section benefits from some drying in winter. The proof of the pudding will come when you bloom it.

    Ok. Thanks Marni. I'll dry it out a bit and see what happens.

    Jon I agree with Marni that your plant looks speciosum-like. In fact, it looks a lot like D speciosum var pedunculatum which does come from North Queensland too. The habitat is monsoonal tropics, so a distinct dry rest in winter is required, plus they tend to grow in exposed areas so lots of light !!
    Good luck....

    PS Jon I neglected to mention that D speciosums are very slow to mature to blooming size - some take up to 15 years from seedling before they bloom.
