Oh I agree with you on the Cycnoches. I just got a cooperi seedling this year from SVO and am super excited about it. Apparently the female flowers are long-lived! Stephen Van Kampen Lewis featured his on his youtube channel this week.
As soon as the SVO list was updated, I got three cooperi. It soon sold out as expected.

I would have bought twenty had I enough space to grow & bloom them all as I love these swan orchids.
All three are in bud/spike at the moment. One is about to open up any time now, the other plant will be ready to open in about one more week, and the third plant is busy growing the spike. I'm glad that all three look very different in plant shape too. One is thin and tall. The others are short and chubby. Looking forward to see at least one plant which turns out to be very dark in bloom like the parents used to make this cross.
Yeah, I saw the video.
The only time I've ever seen female flowers on my Cycnoches, it was my Sevenfold. As a first time blooming seedling, it made 3-4 large female flowers. They do last much longer than males. 4 weeks vs. 1 week in pristine condition.
The both look basically the same except the female has shorter "neck". I like them both, but I prefer male flowers, which are usually much more abundant in numbers and those long stamen really accentuate the exotic look of these guys!
Good luck with your cooperi!
