    This bright little dendrobe has flattened ( you can see one or more bulbs edge-on in one of the pics) stem-like bulbs flowering from nodes on the shoulders, next to the terminal leaves. I have a couple of plants, the other one has made a much taller bulb which is two spiked, and one spike has 12 buds – so it can do much better than as shown here. I’m not showing the other since it is a couple of weeks later, flowers not yet open. I am sure it can do even better on all counts, but am in doubt on ideal culture. Clearly it likes a quiet rest with no water for some months – which it has had, but what to do then ? Last year I grew it hanging up and watered by dipping occasionally , and maybe it liked that since it seems to have done fairly well – but I always want to do better, so any experiences from other members will be read with interest .

    What bright and cheery flowers! Although the blooms certainly look like dendrobiums, the pseudobulbs instead of canes would have had me fooled - then again, I know there are thousands of Den. species and I have less than a little knowledge about them. Absolutely no experience with this species, although I have a Den. Pompadour and Den. Joyce Nakata, both in S/H. Other than the fact that yours is obviously doing well, is there any particular reason you don't have them in S/H? I realize mine aren't species, but should I be expecting them to keel over soon? They've both been in it for over 3 months and seem to be okay.

    By the way, I mailed off an application for registering a vinicolor paph. hybrid with the RHS today. Its recent HCC/AOS is provisional until the grex is registered, so I was instructed to do it. Originator is unknown, at least to me, the AOS, and the RHS as far as records are concerned. Have you ever done this before? Should I expect a visit from the crew at Kew??? I should think that my credit card being charged the current rate of U.S. dollars vs pounds sterling, as well as the cost of exchange should be adequate to usher the whole thing through, but then the opposite may just as well be true. Now I wait and see, I suppose.

    Lovely den! I have a small sulcatum, but it hasn't bloomed yet. Not sure mine gets quite enough humidity to be really happy. I will be interested to see what tips or advice you get.

    [QUOTE=mauraec;298750], is there any particular reason you don't have them in S/H? . I don't like S/H for anything needing a long dry rest. That's why it works so well for the thin-leaved South American species which mostly don't rest at all , and less well for others. ( I think ! )

    Thats OK that you don't know the originator - then you can register it. If you do know the originator you must ask their permission ( and it's scouts honour about whether you really do or don't know the originator - I think !)

    Thanks for the info - now I'm wondering if I should put my lycaste hybrids in S/H - they aren't yet - both have skinneri in their backgrounds. Any ideas? I know you have at least had one lycaste - a beautiful soft pink, because it's on the cover of your orchid book - which I have, for purposes of admiration, if noting else!

    It is past tense as far as Lycastes are concerned. I gave up growing them about 1975 ! When I did that book I went back through all my slides and picked out 500 of the best pics ... I have never grown them S/H ....and the lycaste experts I know - e.g Henry Oakeley who practically invented them (!) was always a bit sceptical about my S/H experiments.

    I will leave them in peace, then, as long as they behave properly(!) Thank you again for yet more bits of wisdom. My lycastes may well be past-tense as well, but I am speaking kindly to them at present. I shall look up some info about Mr. Oakeley.

    For years I have avoided growing this delightful den, believing that they like cooler conditions than we have here, but recently I succumbed to the temptation and bought a bare-root division because the vendor assured me it could bloom here. It has put out a spike now with more than a dozen buds, though no new roots that I can see. I know that I should not allow the spike to develop further to conserve energy, but I just need to enjoy my first sulcatum blooms!
