Hi everyone, I stumbled on this forum and have been reading through all the super helpful threads.

Here's a question that I'm hoping someone may be able to help with. I may be overthinking it, but my pastazanum's stem isn't crawling but instead growing upwards!

From what I can gather, the P. pastazanum is a crawling type Philodendron that has a stem that creeps along the ground from which petioles emerge and shoot upwards.

I got the plant with two leaves growing from the end of a short section of stem which looked like it had had some cuttings taken from. It was originally in sphagnum moss so I planted into a terracotta pot with the stem horizontal and leaves vertical, leaving the stem peeking out the substrate and with some room so that the plant could creep before encountering the other side of the pot.

It has since grown quite quickly, three new leaves in the past 1.5 months and with another on its way. However, the new leaves are from a stem section that is pointing upwards instead of horizontal! The stem has taken a 90 degree turn from the original bare stem that the plant came with. I've attached some photos to illustrate this.

(I added a chopstick to support one of the original leaves because with its really long petiole, it had a tendency to lean a bit. Don't know if that's affecting things.)

I'm wondering if there's anything wrong with my plant. It seems to be happy, putting out new leaves constantly, but I'm worried that if it keeps growing up, it won't be able to support itself. I thought that the plant was supposed to be able to orient itself to grow along the ground...

Any insight would be much appreciated!

That is normal for Pasta. Its a creeper, yes, but it can also form something like a clump. It should eventually start laying down and growing along the top of the soil. Some creepers grow on top of the soil, some grow under the soil and send up leaves at intervals. My Gloriosa, Plowmanii and Mamei grow under the soil and pop up like that. I don;t have Pasta, but used to grow McDowell. McDowell was a surface creeper, like Pasta.
