There were a few of these plants next to each other, but not all of them had this bright purple coloration. I suppose there might be an acidic spot by the roots, but I’m not sure.

    I agree!

    The Wiki page points out that:

    The younger leaves of Chenopodium giganteum are hairy with a magenta colour and the older become green.

    But it doesn’t go into what the pigment is, or why they might do this…
