That's fantastic, Frederico! I really love harrisoniae. I have a semi-alba flowered plant that should be blooming in a couple of months from now. And I got a small alba flowered plant last winter, but by the time it arrived it was going out of bloom. So I'm looking forward to it flowering this winter. I didn't realize this species could flower from such small plants. My semi-alba is pretty big (though not as large as the plant pictured in your photograph), but the alba is small, but was still carrying three old blooms when I got it--and they were still highly fragrant even though they were dying! Beautiful species, and it's one more reason to be envious of growers in its native country of Brazil!
In fact, here it's very easy to grow certain plants, especially the native, and this is very good! But cultivating Cymbidiuns, for example, is a problem because the winter is mild and short.
I think the key is not trying to put every kind of orchid together in the same space and to think that is going to work for all; it's better to have a more limited collection, with plants that can grow well in your environment
I agree completely. But that can be a hard lesson to learn. I tried several times to grow Odontoglossum crispum, which I think is a beautiful bloom. But none of those experiments was successful. I have since determined that until I can afford to get a vacation home in the mountains of Colombia, I'll leave poor Odontoglossum crispum alone. :-) Luckily, Bifrenaria harrisoniae is not nearly such a prima donna.
