    These Aussie dendrobes need a long dry and preferably fairly cool if not actually cold rest in order to flower ; otherwise they produce keikis by the score . I do this resting in an unheated greenhouse where I grow other things in the summer ( tomatoes) so it is available from about mid-September onwards. I leave all my dendrobes ( almost all) there until the weather forecast is for temperatures below say 7 deg. C. in the night, then bring them in again. In a bad year - for resting- that means early November. This year the winter was mild ( until a couple of weeks ago) and they stayed there until mid December , and even then got brought in only because I was going away for a week, and I feared a frost whilst I was not there to save them . But up till then, it barely got below 10 , and on many nights only down to 12. If it gets cooler - down to say 6 or 7 degrees for a few nights, then the flowers are white - alba , but this year it was not cold enough for long enough, hence the pale pink colour and the thread name.
    I grew this - and at least dozens of others ( from keikis from the original in years when I was learning how to do it ) from a keiki I begged at a show in 1988.
    They grow well in standing water when the new growths appear, and if in decent potted condition the new canes will grow at least an inch a day. If the summer is warm, better still hot ( by English standards ! ) they will make two or three new canes in succession with a month or two between each - and this from each lead. Moreover they flower for several years from a cane, unless you manage to get them to flower off all the nodes at one go ( don't know if that is possible, actually ). BTW this cultural regime seems to suit a lot of the other Australian dendrobes too.
    Oh, and it has a super scent !

    I didn't realize temperature had such a huge impact on their flower color! Beautifully grown, Geoff!
