Interesting. I've not looked that closely, or investigated to see if conditions affect those things, like the bloom looking more greenish, whitish, or yellowish, or the stem coloring.
But apparently they don't all make the same bloom, if these pics are labeled correctly:

And thinking about it this morning, P. verticillata blooms do branch into "feathers" while other peps just make single-stalked inflorescences. I don't feel like I have enough info to help with an ID decision about the pic in question. I support deleting it or moving it to the genus level if you feel strongly either way.
