From County Cork, Ireland.
One of the interesting features of the grounds around Blarney Castle is the Poison Garden. As the name implies, the plants here are various poisons, including wolfsbane, mandrake, and ricin. There are signs basically warning you to enter at your own risk, and not touch anything!
Pictured here is common juniper, Juniperus communis, a very common ornamental shrub (especially common in Ireland, too). The berries are edible, but bitter. They have some medicinal uses, even possibly acting as a contraceptive or abortifacient. They are also thought to be toxic to dogs.
Remember, the poison is always in the dose!
