Those are Ctenanthe amagris, which are supposed to be very hard to grow from what I’ve heard.
The mother plant also grew this fast, so I made a few cuttings to propagate her.
That’s how she looks now:
I can’t stop them from flowering…
The only issue so far has been that I’ve simultaneously both over-fertilized AND let them run dry while having extremely low air humidity because I forgot to close the window a while ago. This resulted in all existing tips burning, but this hasn’t happened yet again on the new growth.
Yeah, I messed them up… again. I have both a Ctenanthe amagris and Maranta leuconora. I never seem to remember which one is which 😅
Thanks for letting me know!
