Hello Everyone:
Does anyone know the culture of this new species paph vietnamense? What temperature do they like? What type of medium do they prefer?

Paphman

I'm growing this in a seedling bark mix. I look forward to hearing advice from others also.

I don't have this one, but looking at the geography and habitat info from Averyanov, I suspect the culture for vietnamense would be very similar as for micranthum and armeniacum.

High light in winter, reduced in summer. Winter dry, summer wet. Temps down to 50's in winter, 80's in summer. Calcium addition to potting mix with pH in the mid 7's.

I'm new here but I just had to say I don't agree with the neutral pH, they live in detritus and that's certainly not neutral. Perhaps start out with neutral and gradually lower until it appears happy and sprouts?

Esquirolei and concolor are "humus epiphytes" that are found sympatrically with vietnamensis. Recorded soil pH values for concolor range from 7 to 8. PH values for esquirolei range from 6.8 to 7.8.

vietnamense will not grow to its optimal potential if grow together with micranthum and armeniacum. Definitely it likes more watering even in the winter and there is no need to cut water supply especially temperature is kept rather stable indoors. Hugh temperature difference required for triggering spikes for micranthum and armeniacum is not neccessary also. Spikes are sent almost automatically when the plants are well grown to mature size. An experiments was done last year on how temperature and humidity in winter affect vietnamense's blooming. Results shown that there is no significant different on 2 groups of medium size seedlings growing in a room with constant high humidity with stable warm temperature bloom just the same quantity of spikes compared with another group with lower winter humidity and low temperature.

For soil pH, I only have a brief idea how vietnamense likes ... vietnamense has high tolerance against change in soil pH to more acidic level. You will expect root rots for other type of paphs like brachy grown in such a declay medium but vietnamense can simply grow in it for almost one more year without losing too many roots. Of course they will grow much better if new medium is replaced. Hope it helps ..

That sounds just like delanatii culture.

The two look so close otherwise, maybe they are just 1 species 2 varieties?


Kinda like P. lowii. It's found all over the South Pacific It's highly variable, and new species are getting split off of it all the time. It grows in trees, it grows on limestone. It doesn't seem to care what kind of potting mix you use as long as its not rotten. It has no real seasonality. Just grow it and bloom it.

I have been told just to grow it like you would delanatii.

Actually, according to Cribb and Averyanov, the original reports describing delanatii were probably describing vietnamense, as they were from further north than delanatii. I have not grown vietnamense, but it is supposedly easy to grow...but, aside from the pink coloration, vietnamense is very different from delanatii. While delanatii grows in an acidic substrate, and clearly prefers it (at least when I grow it), vietnamense grows on a more calcareous substrate. Also, delanatii flowers last about a month...not overly long for a paph, but still a decent time. supposedly, vietnamense doesn't last for much more than 2 weeks, at least not without curling up. The staminode is different also....again, those with experience can speak up and correct me if I'm wrong...and here in the US only the Wellensteins have that experience (or at least are the only ones who can safely discuss their experience in public)....Take care, Eric

Eric , your descriptions are just perfectly correct !

Thank for the information, Avery and all. I can't wait for my importation from Taiwan to show up anytime. I think I will not have a problem growing them with my Paph roth seedlings.

You can grow them with your tiny little roths seedling but never put them with your medium size roths seedlings which need more sunlight. Vietnamense don't like too much sunlight and they do well with dim light already. You will have beautiful foliage under dim light as well ! Good growing !!!

Thanks Avery,
I forgot to tell you all that I live in Canada and flask of vietnamense can be imported without CITES certificate. Canada's intrepretation of CITES is different from the US CITES. To import a flask in US, the parents of the seedlings in flask must be legally collected whereas in Canada they are not needed to be certificed as beening legal.

Paphman

Good luck with your flask, I hope they all live long and prosper.

Thanks Tadd:
Survival rate depends on the quality of the flask to begin with. I generally do not lose any seedlings to rot unless the flask is jumbled pretty badly.

hi everyone,
I recently bought paph. ho chi minh (delenatii X vietnamense). does anyone know what's best for this paph (soil Ph, light)?
thanks, amber

Grow it like a Phalenopsis conditions. Ph would be about 6.5 to 7 would be fine. I don't think this plant is particular fussy to grow.
