I came across the Silphium plant that went extinct around 64 AD. It is believe that emperor Nero was to have eaten the last known stalk!
It surprised me that such a valuable plant was not cultivated through agriculture.
Are there other plants that we know to have literally eaten out of existence?
Another theory is that when Roman provincial governors took over power from Greek colonists, they over-farmed silphium and rendered the soil unable to yield the type that was said to be of such medicinal value. Theophrastus wrote in Enquiry into Plants that the type of Ferula specifically referred to as “silphium” was odd in that it could not be cultivated. He reports inconsistencies in the information he received about this, however. This could suggest the plant is similarly sensitive to soil chemistry as huckleberries which, when grown from seed, are devoid of fruit.
Literally in the Wikipedia page.
I’m quite surprised that they don’t have the birth control properties of the plant at the very top of the page.
