Thanks for that. I have a large number of the species you've mentioned. A couple of them have some cultural particularities which make them harder to grow for me. I'd add to that list Oncidium sphacelatum, it's like a weed. I have a very large clump which is about to have its largest number of spikes so far (last year's blooms are in my gallery).

In relation to seed, it's something I'm going to try but as we're heading into an El Niño pattern, I'm unlikely to have much success with non-natives. I have some Brassia and Oncidium hybrids that could work.

Our climate can be tough though, even in the wild D. Speciosum can die in massive numbers during a drought.
