Don't have many "indoor" plants potted up but I can take cuttings. I have a Hoya carnosa compacta, Hoya (i can't remember the species name at the moment...I'll check later), a couple different philodendron species (I can tell you which exactly if you are interested later).

HA! Funny Jeff. I think it’s just YOU! :-) Interesting about plant “trends”. I just (try to) grow what I like and find attractive. I never heard about the Pilea peperomoides “thing” until a month or two ago when I saw it near the register in a Chinese restaurant. The owner was telling me that “you can find them everywhere now”, as if they had been hard to find before. I guess that whole frenzy passed my by. I’d never heard about (until it was over...?) it and wasn’t looking. As many nurseries and garden sections as I’ve frequented in the past and continue to visit, I’ve never seen them anywhere else. I came across this post in searching GW for any advice, problems and care instructions that I might find since I just purchased one from an Etsy seller. Both a Pilea peperomoides and Pepperomia prostrate cuttings. No idea where that one is on the plant trend-o-meter either. Just hoping I have luck with them.

Well it sure is great you are able to keep that humidity level for your plants, but in regards to individual humidity needs, nothing there on your list needs as much as Calathea warscewiczii. The Calathea orbifolia comes close, but still needs less. The very bottom end that's usually recommended for the C. warscewiczii is 50% just to survive. The pros use much higher. It probably came from a greenhouse in the range of 70%. It's always possible to keep houseplants at lower than their recommended humidity levels, with excellent watering, and grouping with other plants for localized extra humidity, but there is something you should know about the way the leaves develop. There is an effect in many plants where it will grow leaves "tuned" to the ambient conditions while the leaf is forming (i.e. 70+% greenhouse). They can grow new leaves tuned to much lower levels (maybe in the range of 50%), but in some plants it can be impossible to change the humidity resistance of a leaf after it is already developed. So you may want to try to keep those leaves alive as long as possible while you wait for newer, more-hardened leaves to develop. Meanwhile you'll want to use every trick in the book to raise every little bit of humidity you can: grouping plants, gravel trays, turning up the humidifier, frequent leaf washing, etc.

Oh, thank you, I really didn't know what I was doing when I posted. Thanks for answering me. I would have been lost without this name. Will check out the growing information. Have a Blessed Christmas, Carol
