Common Name: Enchanter's Nightshade (Enchanters Nightshade)
Latin Name:Circaea spp.
Family Name: Onagraceae
Despite its common name, Enchanter's Nightshade is not related to other plants called 'Nightshade' and is not particularly toxic. It is high in tannins though, and these astringent compounds often give a plant a bitter taste, and if eaten in large quantities can inhibit the absorption of iron and calcium and cause digestive problems.
It should, however, be fine to feed sparingly or very occasionally, as part of a wide and varied diet.
