Hedera helix is an evergreen climbing plant that is native to Europe, Western Asia, and North Africa. It is a woody vine that can climb to heights of 20 to 30 meters (65 to 98 feet) in trees, cliffs, and walls. The plant has dark green, glossy leaves that are typically 5 to 10 centimeters (2 to 4 inches) in length, but can grow up to 20 centimeters (8 inches) long in mature plants. The plant produces small greenish-yellow flowers in late summer to early autumn, which are followed by black berries.
