Hi all: a little update, the plant I asked about in 2020 does appear to be a monstera
However, I need to get rid of it for various reasons beyond the scope here. It seems I have some options:
1. Plant it in the ground in spot that gets full shade (under outdoor steps), but some wind
2. Break it up into 5-6 smaller plants and sell/give them away.
#1 is appealing because there's a hydrangea that's been completely failing there since 2019 (powdery mildew kills the leaves no matter how much I try to baby it, but it somehow it sporuts new growth each year) and I've been too lazy to replace it. I'm coastal so cal, I think zone 10a? Occasional winter temps get to the upper 30s F (2-3C), once or twice in the last several years we got to just around freezing. Would it survive?
#2 is not appealing because I am lazy and don't want to go buy more soils and pots.
EDIT: I did read ES's earlier comment in this thread that they can grow in Arizona and tolerate the near freezing occasional temps.. hmmm.
