Can’t remember the name now, but there is a huge leaf plant that is invading areas and is highly toxic causing bug problems if touched. MayBe “Hog Weed”? It was a long time ago I read about it.
Yep. We have Giant Hog Weed and Wild Parsnip. Both can grow 8-10’ tall and are usually found in roadside ditches.
If you’re cutting them back and get the ‘juice’ on your skin, that juice, when exposed to sunlight can blister you up in a very painful way.
So if cutting it, you need to cover yourself well, wear gloves, eye protection, the whole works. A Hazmat suit is pretty much needed. Nasty stuff.
Another one is Gas Plant - which is beautiful when in bloom, but also causes blisters and burns to those that are allergic - usually light-skinned redheads. Don’t know why anyone plants them - they really DO smell like a gas leak if you dare to get close enough in the first place.
