You could check with Sunset Valley Orchids ... the home of Fredclarkeara After Dark ... not sure if the cultivar 'Black Pearl' is available, but they have bred other dark flowers in the Catasetum group. The website has mostly (or completely) seedlings, but they might have some things in bloom (or better, close to bloom, blooming ones would be very difficult to ship) since we're heading into show season and they do sell blooming plants at shows. (If already in bloom, probably not ship-able, the slightest jostle makes them eject their pollinia and then the flowers fade, but in spike maybe)

You could contact one of the big Cymbidium growers and ask what's in flower now, or what's coming into flower soon. Santa Barbara Orchid Estate, Casa de las Orquideas were mentioned above.

Certainly worth the ask... I doubt that the really dark ones would be in bloom now... just not their season but it doesn't cost anything to ask.

Thank you both (in fact, all three of you!) SO MUCH for the information! I knew I came to the right place.

I hope to be a dedicated flower grower someday, maybe this is how I'll start.

Once you acquire your orchid, this is the place to come for plenty of information as to how to grow it!

I will certainly not forget that.
