Wall iris (Iris tectorum)

Iris tectorum, also known as wall iris, contains toxic compounds in its leaves and rhizome, making it harmful if ingested. Additionally, direct contact with the plant can cause skin irritation for some individuals, so it's advisable to wear gloves when handling it. Despite this, wall iris is a popular ornamental plant in gardens. The name "tectorum" translates to "roof of the house," reflecting its historical cultivation on rooftops in Japan and China. This tradition highlights its cultural and historical significance in these countries.
