Oncidiums with huge pseudobulbs?
 

:hello I have a possibly odd request... Could I get a list of oncidiums/hybrids that produce some of the biggest pseudobulbs? I'm not sure what it is but there's something about an Oncid with enormous plump pseudobulbs that just brings me joy. I've got (and at one point had a much healthier) Onc. Sphacelatum and it's magnificent, I'd like to have more just like her but perhaps with some variety :biggrin: For some reason I'm attracted to the biggest and the smallest of everything, especially with this genus. My windowsills are sprinkled with most miniature varieties I've been able to get my hands on but the biggest guys are harder to come by!
I'm growing in a full south exposure windowsill, with shades up between the glass and the orchids. It hits highs of about 85 in the summer and gets down to roughly 45-50 in the coldest nights of winter, decent humidity (55-65%) and what could be considered high light, though I've got a desk a little away from it that's medium shade. First true post to the forum, figured I'd get it going with a bang!

A well grown Sharry Baby should do the trick.

Anything with Brassia in its heritage will have large pseudobulbs. And look at Peristeria elata, if you have room for 3 foot + / over 1 meter leaves. It's not an Oncidium but the pseudobulbs are amazing.

Funny that you mention it, I've actually got a Sharry Baby in an 8" pot that's just about my pride and joy, she threw 2 flower spikes this go around and is just maturing 4 new growths so I'm sure I'll see more blooms by the end of the spring :) I've mainly got miniatures going right now, my Twinkles and Tsiku Marguerites are going wild and my bedroom constantly smells sweet.

I've had some Brassias in the past and loved them, working to build my collection back up. Disaster struck last winter, taking me from 130+ orchids down to 3 quite literally overnight... I'd moved everyone outside because the forecast said it was supposed to stay in the high 40s, when in actuality it decided to hit 19 degrees that night... :((I'm still not sure how the three survived but I suppose I'm not meant to question it, just thank my lucky stars!

Odcdm. Tiger Hambuhren ‘Goldilocks’ AM/AOS X Oda. Jubilee Volunteer ‘Royal Flush’ HCC/AOS. Got it from Cal-Orchid, who got it from Tom Perlite of San Francisco.

Also, oncidium excavatum.

Just two that I happen to have.

Also, it depends on what you consider large.
