Fluxweed - map locations

[Scourge]

I know that you can buy and grow it from seed, but I'm wondering is there are locations on the map you can find growing fluxweed (outside Hogwarts)?

Not that I'm aware of think growing it ourselves is the only option. That or I haven't run across it and I'm running out of unexplored stuff

I'v occasionally found plants that we can grows ourselves in dungeons, but i can't say for sure which dungeons or which plants
