Heracleum sosnowskyi in Ukraine. Fucking commies decided to start seeding it en-masse for cow feed without even checking whether it would work.

It bitters the milk, making it unusable as feed. It is poisonous and hybridizes with native edible species. Skin contact results in horrible blisters that tend to not heal cleanly. Its juice is toxic and mutagenic.

A war crime in plant wrapping.
