Good luck & good vibes!

Need better location. Indirect light, not shade. Excellent plant for indoors.

That spot gets much more light than you would think, it is by a Western window with full exposure and no protection. My friend's parent plant I got this off of lives in a basement with one small window covered by a curtain. If it where mine, it would have different conditions but it's not. This little offset has very young and tender leaves, trying to adjust it gradually to more light. I just didn't want to burn the leaves. :)

Kim....keep us updated on your progress.

I will do that! Hopefully the spaghnum does its job, I have found it helpful for certain hard to root plants and it came up on a prior thread for rooting these. The other one had much bigger leaves, will just have to wait and see what this one does.

Tropicbreezent, this one grew roots just fine.

However, as you can see that one was much more established than my little guy, no roots but larger and with more mature leaves. I suspect this adventure of mine will result in me having to follow your advice and wait for one of the other offsets to mature, but all the same I can't give it up without at least trying. :)

Sounds difficult...but a philo can root from just a leaf stem. I never had the opportunity to try.

Kim, Meconostigma Philos, the group to which P. bipinnatifidum belongs, need to have roots or roots beginning to develop on a cutting for it to grow. The link you gave shows they had developing roots -
"........... There was originally an aerial root growing from it .........."

Anthonysears, the petiole (leaf stem) can't root unless it has at least part of the main stem attached.

Even if anything will root from a leaf stem, you won't get a plant out of it. A leaf stem has no way to produce any leaves, stems or branches.

Although not an aroid, I had a leaf break off a Hoya that I put into a pot. No expectation of it developing into a plant but it has surprised me in that now after over 4 years it's still alive, has a dense root system, but no sign of a developing plant. But I've never heard or seen any reference to that having happened with a Philodendron.

Hoyas will root and live from single leaf cuttings, but will not grow any new vines or leaves unless there is a bit of the stem itself connected. With my larger leaved Hoyas, whenever I accidentally break a leaf I will root them to fill space in the base of the pot. Which makes those single leaf cuttings of Hoya kerrii a bone of contention with Hoya growers, as few suppliers of them actually get any stem tissue in the cuttings.

But Hoya are very different from these plants. I am already planning on snagging another offset later, but not throwing this one out until it is good and dead.

Tropicbreez.... I've never done it before...
