Paph supardii 09

[Roy]

I found it likes less light and cooler temps than roth and lowii, but more than sanderianum.

Rick, I've read and been told that sanderianum requires lots of heat and to some degree a lot of light to grow and flower, is this not true ?? What temp and light does it require ??

I haven't flowered any sanderianum yet, but I've lost a fair share looking for that sweet spot in the GH. The survivors had real slow growth until I tucked them into the shady area along the center isle of my greenhouse. They hang out the side of the pots into the direct breeze of the wet pad, but shade wise its pretty high. Given the position in the GH, if they get more than 3000 fc its only going to be for a few hours in the morning. Temps where they are will not exceed 85F, and the humidity rarely gets below 70%, but is usually over 80%.

Winter temps can get down into the low 60's/high 50's.

In comparison to other orchid groups, I rate them closer to Phal conditions rather than Catt conditions that other multis seem to thrive under.

They turn out to be real fast growers under these conditions for me.

Thanks Rick.

Beautiful Rick. Look forward to seeing the whole spike in flower.

Interesting that you have found it easy to grow. Makes me wonder why it is so rarely grown.

Because it is rarely propagated, only a few seed capsules around the world gave commercial quantities of a few hundreds plants. Back a couple of years ago there were big batches of that and kolopakingii in Florida and Hawaii, all from a couple of seed caps... Before that all the mature plants in the trade were wild collected, and it is not an easy species to establish, they are very prone to rhizome rot, like all the multiflorals. There are two types of supardii, a compact form with 2-4 flowers per stem, and a large form with up to 10 flowers... Nowadays it is a very rare species in the wild due to deforestation only.

Very nice one btw...

Great color on this one. Hope ours (yours) turns out as well! They tend to grow slowly until they get to a ten inch to twelve inch leaf span, and then take off. Good job growing it.

Thanks,

Looking good.

I'm really looking forward to it blooming too Tom!

I'm not sure if I just had an exceptional batch or hit on some special conditions, but the selfings from this plant have been consistently fast growing. They came out of flask in April 08 and several are already 7-8 inches across, and the first one to go into the GH from inside is pushing 10 inches. I've been keeping seedlings longer indoors under lights than I was a few years ago. Allot of others that I expected to go real fast like lowii and philippinense shot up to 3-5 inches very quickly, but virtually stopped after moving them out of compot and into the GH (with substantial losses at that point). So I'm trying to build up my low light space to accommodate more seedlings to a larger size before taking them into the GH.

Great shape and colour!!! I love it!

It's beautiful!

Looks good. The colour is very sharp.

LOVE IT! Makes me want to run out & get one! :drool:

I got a compot not quite 2 years ago, the largest had l.s. of 4-5", they're now up to 11-13". They get sun til noon, minimum night lows of 55, minimum daytime lows of 70. Phals do awful for me, I felt it's not warm enough for them in my GH, but the sands aren't complaining!
