We've had some Pellionia pulchra where I work. Not quite the same thing, I know, but it's the closest I've got. Everything I've seen about them makes them sound best suited for terrariums: humidity and light are fairly critical. They've done fine in the greenhouse, though they're not especially quick growers, and I don't have any experience trying to keep one at home.

"It followed me home, Mom, can I keep it?"

The person at Logee's said P. repens doesn't require humidity, and that they'd had it in the office in a hanging pot for years and had to use the machete on it periodically. I guess time will tell.

Thank you, mr subjunctive!

I'm growing both Pellionias, and like mrsj....I've always read the require high humidity, but I've discovered that they don't.
When I first got a small one years ago, I tried pampering it and giving it high humidity...it rotted away. (I'm not sure I provided adequate light that time, however.)

My P. pulchra is on a high shelf with only a fluorescent light above it.
Granted, it's not a lush and lovely specimen, but it is holding it's own.

My P. repens is also on a high shelf, but does get some indirect light from the east and west. It's actually doing pretty well.

Both seem to prefer their soil to dry quite a bit before watering...at least when grown indoors.

I did hang the p. repens from one of my apple trees the year before last, and the growth during that summer was much more lush and the leaves much larger and firmer.
The plant even bloomed when growing out there.

With that said..additional humidity and good light obviously provided *optimum* growth...but aren't absolutely necessary, IMHO, to enjoy these plants indoors.

Thanks, Nan. That helps a lot. And I guess I won't use it to underplant my Spath. "Sensation", which arrived with a glossy-leaved Alocasia as a hitchhiker.

About Euphorbia geroldii, what I find online tells me it's basically an everblooming thornless crown-of -thorns (Euphorbia millii) that gets about 3 ' tall. If I can get hold of one---and I'd probably better wait till spring at this point---and if it does well, I'll post about it. But it's high on my "must have" list.
