Oncidiinae heat tolerance

[palito]

Hello everyone, first post

So I am interested in getting some easy plants like one of those intergeneric orchids with small flowers that everyone raves about: odontocidium, odontonia, vuylstekeara, miltonidium etc etc. I only grow catts and vandas outside most of the year under trees, and the summer temps are over 90F.

Now, from what I have been reading online, for heat tolerance I should only pick plants with Brazilian miltonias in the background like Miltonia spectabilis or Miltonia clowesii and completely avoid plants related to Colombian miltonias.

Is that correct? Or are they all equally doomed under the heat and I should scrap this idea?

thanks

Oncidiums do well here in the tropics - flowering in summer. Having considerable success with Colmanara (Milt x Odonoglossum x Ocidium) here too - though they bloom in autumn, the plants thrive through summer with a bit of shade. Also have Miltonia Bluntii 4n which flowered in the heat of summer. Don't know where you live - but unlikely to be much hotter than here. Townsville

Thank you Townsville. I was looking at temperatures around 95F-35C maximum for a couple of months per year.

Yes - that's us. We go to 40C - but not often. Our rain falls in summer so high humidity at the same time. Winter usually about 29C max but down as low as 12C at night - sometimes. The usual oncs. - Grower Ramsey, Dancing Lady will grow in the garden - as will some epidendrums. I have badly burned some dens. by letting the full sun get at them. I have learned to keep some shade at all times. Townsville
