Any plant of the genus Hedera,
with about five species of evergreen woody vines (rarely shrubs), in the ginseng family (Araliaceae). The name ivy especially denotes the commonly grown English ivy (H. helix), which climbs by aerial roots with adhering disks that develop on the stems. English ivy is frequently planted to clothe brick walls. The stems bear leaves with three to five lobes; as the stems reach the top of their support, they become horizontal or hang, sometimes developing unlobed (entire) leaves and small greenish flowers. Numerous cultivated and geographical varieties of H. helix exist, including many with variegated leaves. Native to Europe and much of Asia, this genus has been introduced into many parts of the world.
Many varieties of ivy are cultivated in gardens. Growing them is an extremely simple matter, as they will thrive in a poor soil and endure a considerable depth of shade, so that they may with advantage be planted under trees. For example, the common Irish ivy (a variety of H. helix) is often used as a ground cover beneath large trees where grass has difficulty in thriving. A strong light is detrimental to the growth of ivy, but there are few hardy plants that may be compared with it for variety and beauty that will endure shade equally well. Ivies, in their many forms, are also popular houseplants.
A question of practical importance is the relation of the ivy plant to its means of support. A moderate growth of ivy is not injurious to trees; still, the tendency is from the first unfavourable to the prosperity of the tree, and at a certain stage it becomes deadly. Therefore thegrowth of ivy on trees should be kept within reasonable bounds. In regard to buildings clothed with ivy, there is nothing to be feared as long as the plant does not penetrate the substance of the wall by means of any fissure. Should it thrust its way in, its natural and continuous expansion hastens the decay of the structure. For unrelated plants called ivies, see Boston ivy; poison ivy.
