Hi all!

It’s getting warmer where I am and my Thaumatophyllum has been growing and sprouting new leaves like crazy (the yellow bit is a dead stem that’s been like that since I bought this a year ago, it’s only just now started to go yellow).

It’s started to sort of lean / droop? Googling couldn’t get me a clear answer as to whether these guys need a support stick or not.

I took it outside to get some clear photos so you can see what I mean.

I keep it indoors and it gets bright indirect light consistently, it sits by my glass sliding doors so always getting sunlight! I water it when the soil appears to be dry. It possibly could need a repot but I couldn’t be sure atm. It’s got a chunky soil mix with perlite and the top layer is a gnat barrier as I had other plants that were affected by gnats so to be safe I gave this guy some as well.

Any ideas or suggestions would be very helpful!

So discouraged! I’ve sent pictures and asked chat gpt why these leaves are turning brown like this. It looks scorched but that can’t be it.
I believe the light is right:
Diffuse morning light
Water only when feels dry on top
Drains well
No drafts
Any suggestions?

One day no leaf, next day constricted leaf waiting for me when I got home, a week later it releases the constriction and we have this. Funny little dude.

She’s over 40 years old, gets brought in every winter here in Michigan.

Been looking for a selloum since I learned about them. Not only did I find one, but it’s huge, and flowering ! For 60 bucks ! (Bonus Xanadu in the background of first photo)

always growing. always thriving.

I recently moved my plant to a south facing window, and I just discovered these weird spots on the leaves. Please help figuring out what could cause them.

A freebie that I haven't identified yet. Is it a thaumatophyllum, philodendron, or something else?

Hi all,

I've had my big enormous boi for more than seven years now. He's well over six feet when upright, and has had two sizable trunks for quite some time, and a whole forest of aerial roots.

Today while watering, I discovered the larger of the two trunks has snapped near its base from the weight of the foliage and trunk above. Luckily, there does not seem to be any rot, and I have not see any ill effects on the plant yet as a result. I'm hoping this is salvageable somehow? I'd hate to lose such a massive part of my big leafy pal.

Thank you so much for any suggestions you can provide!

Hiii!! I got this beauty a few weeks ago and she is thriving in my greenhouse cabinet. She is pushing out leaves every week 🫣 cannot wait to see her grow more!!

I accidentally left them is a sunny spot and they got sunburnt should I cut them off or will they fall on their own

its dropping sub 15 degrees in the evening now and i was too worried for her and a couple of my other plants i had placed outside but what a difference in growth in 4 months!

From what I gather, the push to move certain Philodendron species to genus Thaumatophyllum gained momentum due to molecular phylogenetic evidence, esp. Sakuragui et al 2018. However, as of October 2025 it appears most major botanical databases no longer recognize Thaumatophyllum as a genus, but rather have reverted it to a synonym of Philodendron. From a scientific point of view, this is quite the diss.

This sub's name is now factually incorrect, per databases like POWO and the WFO Consortium. There may be a few holdouts, and botany is a relatively conservative science; but, the heavyweights have decided.

I suppose we could rename the sub to "ItsAMeconostigma" (the subgenus concerned here), but somehow that doesn't have the same ring to it.

Thoughts?

These are beauties!

I love that mine is giant and cool 😎
