Ivy

Ivy is a climbing plant known for covering walls and buildings with green leaves. It uses tiny root-like structures to grip surfaces and climb. English ivy is the most common type. Ivy can grow on walls, fences, trees, and along the ground.

How Ivy Climbs

Ivy produces tiny roots along its stems that stick to surfaces like glue. These aerial roots can grip brick, stone, and tree bark. Ivy can climb over 100 feet high on tall buildings. It grows toward shade first, then toward light once it reaches the top.

Ivy in Nature

In the wild, ivy provides shelter for birds and insects. Its berries are food for birds during winter. However, ivy can harm trees by blocking their sunlight. In some places, ivy grows so fast it is considered an invasive plant that is hard to control.

Fun Facts

• Ivy can live for over 400 years.
• The tiny roots on ivy stems produce a glue so strong that scientists are studying it.
• Ivy-covered walls can actually help keep buildings cooler in summer.
