Dendrobium vannouhuysii?

I grow it too. Where have you heard it is a terrestrial?

 

Orchids of New Guinea lists it as a terrestrial, but I would suspect at that elevation it is simply growing over moss covered surfaces as an alpine plant and doesn’t really care what is under it. In cultivation, I would say it’s still best treated as a wet loving epiphyte.

I have been growing mine mounted (vertically) for quite a few years and they are very vigorous, putting out a lot of aerial roots as they sprawl. I have recently put some on vertical mounts and am thinking about a large, flat wooden basket as that may be the best way to get a large mat of foliage.

 

Only occasionally has it bloomed...partly why I’m trying pieces in slightly different conditions. Primarily brighter and even cooler, but also on the larger flat basket as maybe it’s one on those “ground covers” that likes to get to a certain mass before blooming...maybe like Porroglossum eduardii?

 

Chuck, have you noticed the plant being stressed with higher summer night temperatures? I know of a person who grows this one in Minneapolis in a greenhouse without any extra cooling. Other growers say that is purely a cold grower.
I keep mine in a wine cooler during summer but would like to move it to the greenhouse, if possible cause it's getting big.

 

I grow mine in a terrarium on a 45° mount. That terrarium is inside a greenhouse. It gets a mister and fogger. Gets pretty warm in the summer here, with night temp probably at significant value.

I received it as a cane with a few growths and it has 10+. Not sure what critical mass it needs to achieve to flower. I can’t wait though.

 

Thanks, now I feel more confident about trying to grow it in a greenhouse year-round. Does it get to the high 60s at night in your terrarium, what do you think?

 

Hi, I’ve never noticed any summer stress at all. I do have an evaporative cooler plus an Aqua Fog 700 that is connected to a rainwater cistern...so I am able to temper the very hot days

 

This is just Sacramento average for summer. This past summer there was a historical heat wave and this species stayed in an area no where near the cooler.
June. 89° / 59°0 days
July. 94° / 61°0 days
August 93° / 61°0 day

 

hi all, I was wondering how you managed to acquire this one? I have been searching for years in the UK but can't find any at all. which is a real shame because its probably my favourite orchid in the world! With a unique growth and way of flowering.
If anyone knows where I can buy one i'd be smitten!

 

Try choosing a different favorite orchid in the world! LOL

 

lol! if only i could do that!

 

but do you know anywhere i can buy one? Been searching for a few years now

 

oh right, I guess he's the guy. hope he ships internationally
