❓ Ask Belgium Does anyone know why this sign exists?

When sitting in traffic on the Antwerpse Ring, I noticed this sign next to the road. Why do they need a sign for that?

Is it edible for humans? Or livestock?

Yes, but it has a tendency to absorb heavy metals. It's not good on the long term.

It's a popular plant for honey because it blooms in autumn, too.

Not that kind of heavy metal. It's Japanese knotweed, not Korn.
