Inktober 31: Viscum album
(European mistletoe, common mistletoe).
Poisonous: entire plant.
Symptoms: inflamed eyes, dilated pupils, slowed heart rate, hallucinations, coma.
Fun fact of the day: European mistletoe is more toxic than American mistletoe, which is in a different genus (but same family) of plantae.
Also you get a xmas plant for Halloween because xmas is just full of toxic goth plant decor as far as I’m concerned.
