I have trouble growing this sp. well in wet tropical conditions , so I imagine it would be difficult to grow well out of a glasshouse elsewhere .

Thanks, aroideana. I think I'll wait a bit on this one. But I do have to tell you that you are responsible for the latest plant I've purchased (online, so hasn't arrived yet), Rhaphidophora cryptantha. You mentioned this plant in another thread, I was curious, so I checked it out, and was amazed by its growth form, and I eventually tracked one down. Any tips for this one?

Cheers,

Alan

Alan , the cryptantha will grow in very bright light as well as deep shade , it likes a rough/solid surface to get a grip on .. mine is growing on a grapefruit tree in deep shade .. pics on IAS are out in bright light on a very smooth palm trunk .. I think it needs high humidity for best growth .. does not really need roots in the ground .
I have heard of some being grown on glass ! I have seen it growing on granite boulders as well , but for some reason it [ the foliage ] stayed very small.

I have a 3" diameter PVC pipe that I was going to use as a totem, wrapped in either shade cloth or perhaps some coir liner.

On the other hand, you're almost describing an epiphyte here, and so I may need to ramp up the humidity here slightly, and the PVC may not do the job...

I grow Philo. verrucosum in a greenhouse up a moss-pole without any problems here in the UK. I have found it fairly easy to grow and mine was an import from Ecuagenera. I have found Philo. Melanochrysum much harder to grow and would be grateful for any tips.

Maybe you could seal up the base of the PVC pipe with a cap, then bore some fine holes to weep out and keep the fibre wrapping moist ?

I have all 3 of the plants you have mentioned. My R. cryptantha is still in a container not climbing on anything. I haven't gotten around to it yet but hope to actually get it in somewhere on a totem this week.

My Philo melanochrysum is climbing very well. It is about 3 years old and has been a very slow grower for me compared to other philos I have. It has gone about 4 deet up the totem and its leaves are finally about 8" long.

Philo verrucosum has not been particularly demanding. I got it onto a totem right away when I got it 2 or so years ago as a pretty eentsy plant, now it is at about 8 feet up the totem and the leaves keep getting bigger and bigger. I just added another section onto its totem today as a matter of fact to give it somewhere else to go. Here it was before the new totem was added

This is my P. melanochrysum. The funky looking aroid to the left with the long pointed tongue is Epipremnum "Skeleton Key"

When verrucosum matures it does not look anything like it does when young ! I was very surprised to see the white veins gone . That SKeleton Key is not around down here Gina ,, hope it gets imported one day .

I think that it was very very rare for a long time. According to the person who I got it from (if I recall the story correctly), it was only known in one collection, and that person who had it wouldn't let any of it go for a long long time. Then when they finally did, it took a long time before any was made available for sale. I think its still fairly rare. It has to get a lot of size on to really look impressive. Mine is only just starting to get really big and develop the "keys".
