Here's some pics. I previously posted trying to get an ID just from the cutting that I got, but this is my grandparent's pic. Someone suggested that they could be Giant Hawaiian Pothos, and another suggested some type of philodendron. Any ideas?

I'd say Epipremnum pinnatum ("Golden Pothos").

I've seen mature specimens of the common Pothos house plant
grow to that proportion when planted in the ground in South Florida.

thanx zuzu!

This one started growing on the tree, but was not successful just on the ground. My Papa said it got in the way, and he just threw it up next to the tree, and when he checked on it it had started growing on the tree itself. I'd like mine to get to this size, but we'll see.

thanx again!

that their leaves become so much larger when climbing up a tree.

thanx!

I didn't know that about Pothos plants. This is my first one, and I would love to get it as big as my Papa's.

I'm looking it up on the web. I'll let you know if everything checks out.

Thanx again!

I think that's it!!!
