Mullein
In 322 BC Aristotle noted the exceptionally useful employment of mullein (verbascum thapsus) as a piscicide (fish poison) in his Historia Animālium. Gabriel Garcia Marquez also noted this use in Love in the time of Cholera 2307 years later.
Dandelion
Of course such a thing couldn’t stand for long and so Hecate, the goddess of the knowledge of herbs fed the heroic Theseus Taraxacum (dandelion) greens for 30 days before sending him into the monster’s maze.
Princess Tree
Originating in central and western China, the Princess Tree (Paulownia tomentosa), is often unsurprisingly described in both orientalist and misogynistic terms: showy, aggressive, ornamental, persistent, exotic, and invasive. The Princess Tree is my personal hero.
Horseweed
Meanwhile, the goons at Monsanto thought they would counter by spreading more of their toxic agent. But to no avail and there are some reports of Superweeds growing up to three inches a day.
