[Harry Potter] Where do the magical plants grow in the wild? Why haven't any muggles discovered them?

All of the plants I learn about in Herbology had to come from somewhere in the wild, right?

Muggles are stupid. They will go out of their way to think that something magical is mundane. So, most of the strange things that they see go unnoticed. 

Truth is, magical plants grow all over the world. You just have to know where to look. In the case of something like a mandrake, you would have to dig it up before you can even tell that it is strange. Don't see many people wandering around uprooting random plants now, do you? With other, less savory plants...well, lets just say the ones that meet those don't usually go home and blab about it. Even if they get away and want to tell someone, we have people who have dedicated their lives to protecting the magical world. You get pretty good at performing memory charms when you do it as often as they do. 

Plus, in the case of heavy magical activity, we tend to "rope the area off" so to say. Charm the landscape, and suddenly people just see thorny underbrush. Don't want to go in there of course. Or they just forget and go another way without noticing. Kind of like Diagon Alley. Depends on where they are and how dangerous the thing we are hiding is. Sometimes we even have to uproot them and keep them in our own greenhouses, or just torch them if they get out of hand. Gotta watch it though, some of them don't appreciate being torched!
