Read about 20 of the best evergreen climbers.
English ivy has two phases of growth. When it's young and in its 'juvenile' stage, it grows up and cling to surfaces via the tiny roots that grow along the stems. After around 10 years it becomes an 'adult' plant. The leaves change shape, becoming less lobed, and the plant becomes more shrubby. It bears yellow-green flowers in autumn and black berries from winter onwards.
Juvenile ivy plants can also be grown in pots, along with naturally smaller cultivars. They spill attractively over the sides and are especially useful for providing evergreen interest in winter planting combinations. They can be trained and tied around a wire topiary frame – young and compact ivy plants are sold as house plants.
English ivy is also one of the best climbers for wildlife. The green-yellow flowers on mature plants provide a late source of nectar and pollen for insects, and the black berries have a high calorie content, providing food for birds, including thrushes and blackbirds, in late winter. Ivy also provides shelter for birds, bats and small mammals.
Is English ivy poisonous?
English ivy is sometimes confused with poison ivy, Toxicodendron radicans, a North American native climber unrelated to English ivy. However, English ivy sap is very mildly poisonous and can irritate the skin and, if ingested, can upset the stomach. It's best to wear gloves when handling English ivy, and avoid eating it.
Is English ivy invasive?
English ivy is a tough plant that will grow just about anywhere. in some parts of the world, including the United States and Canada, English ivy grows as an invasive non-native plant. This has lead to its reputation for being invasive, although this is not the case in its native Britain and Europe.
English ivy can grow up trees, but this does not harm the tree – ivy is not parasitic and does not harm its host.
English ivy has been found to keep buildings warmer in winter and cooler and summer. However many people worry about its affect on their home. The aerial roots of ivy do not damage buildings, but they can penetrate cracks in old or damaged brickwork or masonry. English ivy needs to be trimmed to keep it away from gutters, as it can block them.

If English ivy has become a problem on your property and you want to remove it, sever the main stem. Let the plant die off naturally, then gently pull the ivy from the wall. Bear in mind that English ivy can protect walls, and so by removing it you could incur some damage. Some aerial roots may remain – remove these with a hard brush. Ivy is not easily killed by weedkiller as its glossy leaves stop it penetrating, and chemicals can have an adverse affect on wildlife.

Ivy is self clinging, which means that it clings to its support via tiny roots (known as adventitious roots) that grow along the stems. It therefore does not need to be trained along wires for support.
How to care for English ivy

Growing English ivy: problem solving
Ivy is generally problem free.
Leaf spots – sometimes dark spots, caused by a bacterial or fungal infection, appear on the plant. They don't affect the health of the plant. Remove any affected leaves and avoid wetting the foliage when watering.
Reversion – sometimes ivy cultivars that have variegated or unusually-shaped leaves will revert to plain green. Just remove these shoots when you spot them. Variegated ivy growing indoors may lose its variegation if it is too shady a spot.
Brown leaf tips – if you're growing your English ivy indoors, brown leaf tips are a sign that the room is too warm or the air is too dry. Move to a cooler spot.
Advice on buying English ivy
- Check the eventual height and spread of your plant – this can vary
- Do not aim to plant ivy up an old building that is already showing signs of damage
- If you're planting in a shady spot, consider a variegated variety to brighten it up
