    does anyone grow Epidendrum rhizomaniacum and if so, how are you growing it?

    From the looks of the plant, it appears to be pendant growing, but there isn’t any information online to confirm/deny.

    Hey there! I some years ago ordered a plant of Epi. rhizomaniacum from Ecuagenera… but when it finally bloomed out it had the ordinary small green flowers of a nondescript Epi. difforme-like species, not the white flowers with broad lips and wide petals as in the pic in their catalog or on IOSPE. I am going to try it again, and have mentioned my experience to Ecuagenera in my order... As to culture: what few references exist online say the plant grows cool to warm; to my eye, it quite resembles the rare and choice species from Costa Rica, Epidendrum mirabile, which is semi-pendant (like Encyclia mariae, say, rather than Encyclia citrina), and decidedly cool-growing. I am going to try to treat it like a Pleurothallid: and like those, as well as most montane species, I will only apply distilled water, both in irrigating and misting. Will let you know how it goes after I get my plant in late July!

    Links to 3 other pics than those in IOSPE:

    UPDATE: The plant received of Epi. rhizomaniacum in summer 2019 came already half-dead, with blackened foliage; the stems didn't last a week before it was wholly dead. In my January 2020 order I made one last attempt. This time it came with only a few black leaves... in the six weeks since then, I have it potted in a clay pot in NZ sphagnum, and so far as today it is still alive; it may even have grown very slightly. But it's not out of the woods yet... more updates to follow.

    The foliage itself is tender and a tad floppy, which is likely the reason for its susceptibility to black rot. It reminds me indeed of what I have seen of the foliage of Epi. mirabile, and also a tad like Epi. ilense, though that foliage is sturdier.
