It's not getting enough light, hence the flopping foliage. Needs a window.

Wow, that's easy. It is next to three south facing windows that get a ton of light. I think my cleaning lady and I have been keeping the blind down in there while we are out of town. (It still gets light in the room with the blind down but I guess just not enough.)

I selected this plant specifically because this space was too bright for other plants. Unobstructed south facing windows on an upper floor in Manhattan. You can sunbathe in the winter in this window!

That one spreads anyway.

@Sherry8aNorthAL - So are you saying the way it is now is just the way it is going to and should be? I shouldn't adjust the light or try to steak it?

I would not stake it, but give it as much light as possible.

I cannot tell exactly which one it is, but care is about the same.

It is a philodendron selosum.

If you want it to stretch up more like the last photo, have up a way to put a grow light over the top?

Im not dedicated enough to rig up a grow light. :) Maybe I can try finding some kind of way to stake them and keep rotating it towards the light. The window is on the left side of the plant.

A pepper cage should work.

Were it my plant, come spring I would cut half the stems back by 2/3 to encourage new, bushy growth. Once these were growing well, I'd do the same with the rest. The leggy plant you have now will never look good.

Mine is always thirsty. I give it a lot of water. It doesn't flop, but I have trunks on mine.

Please don't cut the stems in half. They are actually leaf petioles. They will not produce branching if cut. They'll just die back.

floral is correct - do not cut back! This is technically an epiphytic vine and can develop into tree-like proportions if grown in the wild.

If the flopping bothers you, cage or support it in some fashion. Or, provide a couple of moss poles to encourage more upward, vertical growth.

I checked out a reddit forum called r/ItsAThaumatophyllum

If that is what this actually is, they say they are supposed to grow sideways. The are often used more like shrubs in tropical locations because the grow outwards instead of upward. They said placing it lower than my window sill will encourage it to reach up to the sunlight. But, I love where it is now placed in my home.

I think I will get some kind of thing to stake into the soil and tie the thick base parts of the stems to. I also saw these for sale on Etsy. Could work too? Thoughts?

If you want a bushier. less leggy plant you can root stem cuttings in soil or water. Easy to find instructions online.

I think it's really lovely - it has presence - maybe decorate around it? If it were up a bit higher, it could loom nicely over your shoulder on a couch! I've never had one of these.

Anyhow it seems very happy. Thanks for sharing it!
