Which might be more warmth tolerant?
 

Between these Masdevallia hybrids, does anybody have experience with which might be more warmth tolerant? One might grow inside a large glass hurricane vase with daytime temperatures in the 80s F / 26-30C and nights somewhat cooler. I know hybrids sometimes fall far from the tree in temperature tolerance. If I decide to get one I'll do so sometime this winter or spring so they might have a chance to get established while my house is in its cool phase.

M. Cheryl Shohan 'The Babe'
M. Huayna Picchu (seedling)
M. Redwing (seedling)

Redwing is infracta x coccinea. I have read infracta has a wide range from cold to warm areas, and coccinea is a cold grower.

Cheryl Shohan is (veitchiana x xanthina) x Redwing. v. and x. are both considered cold to cool growers.

Huayna Picchu is veitchiana x princeps. Both are considered cold to cool growers.

Thanks.

Huayna Pichu is the most warmth tolerant in my opinion.

I have grown both species that make up the cross.

Masd vietchiana tolerates cool to intermediate temperatures very well, (36 F - 85 F).

Masd princeps tolerates the high end of cool to the low end of warm temperatures very well, (45 F - 90 F)

FYI, Masd xanthina is a cool - intermediate grower as is Masd vietchiana. They both have very similar temperature tolerances.

Masd coccinea can tolerate cool - intermediate temperatures (36 F - 85 F). They can handle 90 F for very brief periods of time and not frequently. If it does go up to 90 F, it must drop down to 36 F to 45 F at night.

I don't have enough experience with Masd infracta to definitively tell you whether it is temperature tolerant or not, but so far to my knowledge, it seems to prefer more intermediate temperatures than either extreme, (maybe, 50 F - 85 F would be safe).

Thanks. During summer they would not likely see nights below 78F / 25C. That is my main concern.

Try Masd ayabacana, Masd reginae, or Masd princeps.

They tend to tolerate warmth better.

1. My first inclination is to ask why you'd want to try and grow something that you know you don't have the right conditions for? It might do well now, but come summer, you're going to suffer watching it struggle, and will end up tearing things up and spending time redoing things.

2. Try Masdevallia Copper Angel.

That's my point. I don't want something that won't grow under my conditions. I don't have any experience with these so I'm asking.

Masdevallia nicaraguae might be worth another try. It is a warm grower though it needs a little more humidity, needs shade and likes moist conditions. I have been growing mine in an open fish bowl for the past year.

Now that I think of it, Masd wendlandiana is also considered a warm grower.

I was thinking hybrids because hybrids are usually easier to grow than species.
