    I am new, so first of, hello everyone!

    I have recently aquired 2 rooted cuttings from Philodendron squamiferum one was a little offshoot with a few small undifferenciated leaves, while the other was a 2-noded head-cutting of a larger plant with one large mature leaf.


    what confused me was that the petiole of the mature leaf was almost completely green while the little offshoot had partially red petioles. They did not come from the same plant.

    What i want to know is the following. Do they all emerge reddisch and later turn green over time? Or do they emerge with different colouration based on the lighting they are exposed to, based on the maturity of the plant, the nutrients present in the soil, or any other factors?

    I could not find any clear information on this anywere but my best guess is that the brighter the light the more red is present on the petioles.


    MfG,
    Wolfram

    Are there any theories what might affect the colour instead?

    Here is a close up, there is a tiny little bit of pink/red on the underside just where the petiole goes over into the major leaf-veins

    Initially i was struck with how red the petioles appeared in most pictures online, which sparked my question.
