Philodendron serpens

I have purchased this plant 3 times and received it 4 times and each time the plant has not survive the sipping and if it arrives alive dies soon after, I have dozens of Aroids all thriving except this one

I picked this one up from a local trade show, and it was looking decent. It had two leaves plus a cataphyll. One leaf & petiole and the cataphyll were in good condition, one leaf was limp and starting to yellow. I cut the yellowing leaf/petiole off after a few days. I had it in a pumice/sphag mix, medium-high humidity, and indirect bright light. A few weeks later, the cataphyll had shriveled, and the stem rotted near the roots so I cut it down to two node-chonks. I have one in perlite, the other in soil. Neither has progressed but they're still alive for now. This is a striking species but it didn't seem to travel or re-acclimate well.

very pleased with this plant! looks healthy with new growth. only slightly wilting from travel but no yellowing.
