    This species has flowers which can hardly be called a good shape, but the startling colour makes up for that. This is a plant which I bought at a Society auction sale, in poor state, but with three leads. Two are flowering now, and the root action looks good, so more next time perhaps.. I am growing it in S/H using Perlite as the medium. It is a Brassia relative and sometimes used in hybridising in attempts to get that colour into a more usual flat flower, but successful attempts seem pretty rare. It is supposed to be a coolish grower, but of course lives in the same conditions as everything else in my greenhouse. The pot size btw is 6 inches which may give some idea of scale - the flowers perhaps 3 or 4 cm across, although such a jumble of petals from the close packed flowers on the stem that it is difficult to see where one starts and the next one ends.

    Well, no longer a Brassia relative, but (for now) a Brassia. Thus its most successful hybrid, Brassada Memoria Bert Field (x verrucosa) is now a Brassia. I think the genus Ada is now a null set.

    You're back from your holidays! What a great welcome it must have been to see this extraordinarily rich and beautiful color - it MORE than makes up for the shape, although I think the aesthetic trend of "flatness" is tremendously, and sometime indiscriminately, overdone. The photos are your usual fine work - very striking close-up.

    Since you've been away, I've begun transferring my phrags and paphs to S/H - all in strictly clay pellets. Can I ask why you use perlite for your auriantica? I am going on vacation myself, for about 18 days in February, and am trying to avert having to have someone "care" for my orchids in my absence, as well as cut down on watering time, and on the risks of overwatering. I hope I am half as successful as you have been with S/H; it's very simplicity appeals to me.


    By the way, I have a Brassia/Ada NOID that is striped orange and brown and it has been suggested to me that it has Ada auriantica in it.

    Hope you had (some) fun while you were away.

    Default Why do I use Perlite...

    I use Perlite for S/H much more than anything else ; it is much wetter than Hydroleca, and suits thin-leaved evergreen orchids which want very little rest - in other words most of the Oncidinae and others- but I have in fact had one large flowered Vanda hybrid in it for some 10 years or more, and it flowers regularly, although that is a mile away from my definition of plants which it suits. Oh, and btw I grow all my Catasetums in it too - but these do need a rest, so here I use it as a "compost" but don't (now) use S/H technique.
    If you try it , get the coarsest grade you can find - Supercoarse if possible, and then wash it to remove the dust and fines. Just half fill a bucket with Perlite, then fill with water. Keep pushing it down under the surface. What floats use, what sinks - or at least what sets on the bottom almost like cement , discard. Top with coarse grit to stop moss etc.

    Thanks for the advice, Geoff - I will be able to put my oncids and brassias in your recommended medium, since I've waited on repotting them while I investigated how best to transition them. I'm really liking the simplicity and clean look of this technique. Even if I have a few unhappy campers, I think I'll try to ride it out.
