Dyakia hendersoniana

[nancy]

Formerly Ascocentrum hendersonianum...by any name, a real cutie. No scent that I can detect, but the flowers have lasted several weeks on this very attractive little plant.
Regards - Nancy

Very pretty , lots of blooms Gin

Had one of those once upon a time. Did well for a time then suddenly died. Quite disappointing. May your lil beauty flourish for years to come.

I sort of think these have a shorter life span. Mine did very well first year, had one spike last year and now just sits moping.

Paul and Ross - I had thought that these were very much hot growing/heat loving. That's all that can survive here (unless one is a loco TXan with an air conditioned greenhouse). Maybe zone 5 just isn't close enough to the outer rim of the warmer edges of paradise for them. Just about everybody here has taken a chance on a miltassia, masdevalia, that kind of thing - they just can't survive. Perhaps this one is the same with your coolishness?

Just how warm does it need to be? I grow Phals, Robiquetias, Chiloschistas, Thrixspermums, etc. indoors just fine. But Dyakia just croaks not too long after purchase. I never even got to see this thing bloom.

Man, if I were you, I'd pollinate this sucker now! ASAP! You never know what'll happen. (You don't have to take my suggestion however, it's up to you.)

Maybe it's a humidity issue, idk. Or perhaps an air ciruclation thing? Is it possible it likes it evenly moist and resents drying out? I know Thrixspermum centipedum doesn't like drying out much at all. And the Thrixspermum have a similar looking root system as the Dyakia, (thin rooted).

Hail, King -
My Dyakia has relatively thick roots for the size of the plant, and wiry. Not vanda-thick, but coat-hanger wire.
I grow this outside most of the year, not inside; I did look it up, and in situ temps are generally 70-90F all year 'round, with RH 85%+ all year. So, hot and delightfully humid. Luckily, we tend to have this buoyant heat and humidity. My home averages 75%RH, so a little dry-ish.
We do get average highs waaaay over 90F, but I think this makes the buds open in flushes along the inflorescence, rather than all at once. Or not.
Cheers - Nancy
p.s. I do not perform reproductive acts on orchids. Gawd knows, I have enough kinks already...

[King_of_orchid_growing:)]

Wow! That's very difficult to reproduce here just by growing outdoors or indoors. I'd need to have an orchid tank or mini greenhouse for this.

No wonder.

My RH is about 60% - 70% all year round. The temperatures that Dyakia likes only happen during the summers and only indoors. Here, winters are much cooler indoors.

Thanks Nancy!
