Does anyone have any interesting notes to share on R. Decursiva and R. Hayi? I went on a trek on Friday and ended up with 3 Rhaphidophora (one for my sister), totally unexpected. I can never find them in stores so I was pretty surprised to see them. Yes, I can look them up on my own but I love to hear from the people who grow them if there's anything special I should know.

And a pink begonia that I couldn't resist. Hilarious!

Thanks! They had two decursiva and one was tall and skinny but the leaves were kind of misshapen and then there was this one that was more round and full with decent leaves. I was tempted to get the tall skinny one because it seemed like I could get it growing on a pole more easily, but I was worried about those leaves.

I am sure it is pricey there, even here they are pricey now.... would love to see how you set them, and the updates. you got a very rare one, even in tropical like my country, the are true collectors items

I didn't think the price was bad, but I agree with you...I'd rather spend my money on plants than any other "extra" item. I have a rule that I don't spend over $30 on a plant and I got 3 plants that equaled under the total of $90 that would be my 3 plant limit. But then I went to another plant store Hilarious!
Yes, after it acclimates I plan to pot it and I'll post some updates and pictures. I'm really happy to have found this one.
The hayi, I'm not sure what to do with that one. I think maybe I should put it outside for now since it's very young and not attached to the wood plank yet. I haven't started researching it yet. In fact, they didn't know the IDs at the nursery. They did suspect it was Rhaphidophora but they said it was a Tetrasperma and they said the Decirsiva was a "cebi" and I'm not even sure what that is. I was fairly certain of what I was buying, but nothing was labeled so there's always that question in my mind.

Maybe they meant Cebu blue, as in the Epipremnum pinnatum? It's clearly not that though. Great find, they're both very beautiful! Not sure what to do with my R. hayi either.

Well.......both need to climb so you need two big totems my child.
I will take photos later today of my Hayi and my Decursiva. I have had decursiva for years, it will creep across the floor with an exposed trunk until it finds a support and they it climbs very quickly, Hayi is a rampant climber. It also does not have to climb to start getting pinnate leaves, but they will increase with size as it climbs. Hayi never morphs into anything else, it just stays like it is and climbs, its a shingler. Hayi is named for Dr. Alistair Hay.

This is my Decursiva (one of them). It is growing on a ponytail palm. I didn;t mean for ir to happen it just sort of wandered over there when I wasn't looking and before I know it....
Its a great support but the plant will eventually reach the top and have to be pruned.

They produce these thick roots called 'clasping roots' That hold them to the support. They also produce longer adventitious roots that go down into the soil eventually

Long view

This one os crawling across the floor in the back of the GH by the cooling pad. It is stuck onto 2 rocks
Thumb of 2020-06-15/Gina1960/b6e02b
It will eventually get close enough that I can direct it up to the pad. I am letting this and my Amydrium grow on the pad.

This is Rhaphidophora hayi. It is shingling up my bauhinia tree. It starts out small
Thumb of 2020-06-15/Gina1960/41f773

And gets bigger leaves as it climbs (positive phototrope) but this is really all it does...it isn;t one of the ones like M. dubia that morph into another form
Thumb of 2020-06-15/Gina1960/6cad31

Most people keep it as a terrarium plant

And this is juvenile Epipremnum pinnatum 'Cebu Blue'.
Thumb of 2020-06-15/Gina1960/4047ed

It will run all over creation looking for a totem then it will climb, leaves get longer as it does but always stay somewhat lanceolate not heart shaped. Will eventually pinnate

That.is amazing. Your decursiva looks like a giant caterpillar or millipede the way the giant trunk vine and clasping roots are shaped. I knew it would get big but that is BIG. And the hayi looks just like what I have. I assume it'll need lots of humidity if it's good as a terrarium plant?

The cebu, I have a few of those and knew they were nuts calling it that. They also called it a philodendron at one point. Oh well.

Thanks for sharing. Beautiful plants.
