Well, personally, plants like Dreamshade and Ground Poppy Dust should be excluded from the Magic category. Dreamshade is described as a nasty poison. It's native to Neverland. I don't know, if one can apply the laws of biology to fictional worlds properly, but doing just that now, I would say Dreamshade is one possible result of a plant adjusted to the environmental conditions of Neverland. Adjusted in countless years of evolution. Of course Neverland has magic, but I would say in this case it's more comparable deserts being warm and dry. The plant Dreamshade tolerates of magic because Neverland has it, maybe even requires it to grow (as far as I know it only grows in Neverland) but that doesn't mean it's magic. I would rather say it metabolizes magic. Whatever the reason I would also say that it's rather due to the locational advantage that it grows near a quell with magic properties. The plant itself has no magic, I think.

Same is with Ground Poppy Dust. Again, I would say it's not magic. In the episode Quite a Common Fairy episode Tinker Bell used poppy dust on Regina. Realizing that Regina says the following:

''Whatever you knocked me out with I can tell it’s not magic. Maybe poppies. But they’re wearing off. And since you had to resort to that, it only means one thing. You don’t have magic''.

Looking on the given examples
