Sitting next to those hollyhocks in the Tuileries I had mentioned a few weeks ago, I found an infamous plant by the name of Ricinus communis, or castor oil plant.
When processed, the seeds of this plant produce an oil that has been used for a wide variety of homeopathic uses. However, the actual seeds, if ingested raw, can be lethally toxic. The deadly ricin gas is also harvested from this plant.
Above you can see the showy seed pods. The seed inside resembles a kind of Mediterranean sheep tick , which is why the plant is called Ricinus (ricinus, in Latin, refers to ticks).
