The sap of the giant hogweed plant is phototoxic; when the contacted skin is exposed to sunlight or to ultraviolet rays, it can cause phytophotodermatitis (severe skin inflammations). Initially, the skin colours red and starts itching. Blisters form as it burns within 48 hours. They form black or purplish scars that can last several years. Hospitalisation may be necessary.[9] Although media reports have suggested that eye exposure to the sap can lead to temporary or permanent blindness, the risk of permanent blindness is not supported by existing research.[19]

Good question. We have them coming into our area now. I thought poison ivy was bad, but this is worse.
my neighbors have lost their mind over this hogweed.
Amazing that such a noxious plant species was imported onto this continent.
Or a salad?
Maybe WeWork folk can serve up some of this at their company picnic.
Would make for a good border “fence”. Cheaper too. ;)
