Hedera nepalensis aka Himalayan Ivy

Hedera nepalensis is known as Himalayan ivy or Nepal ivy. It belongs to the Araliaceae family and is a woody evergreen vine. Its native range runs from Afghanistan through the Himalayas to Southeast Asia. It grows in forests, along roads, and on rocky slopes. In Nepal, it grows on damp stones and tree trunks. These sites lie at heights of 5,250–9,840 feet [1,600–3,000 metres].

Garden vines reach about 10–50 feet [3–15.24 metres] in height. Wild plants can climb 50–100 feet [15.24–30.48 metres]. Aerial roots help the stems cling to supports. Without support, the plant trails across the ground. This low cover stands about 0.5–0.75 feet [0.15–0.23 metres] tall. It can spread 50 feet [15.24 metres] or more. Stems form roots where their nodes touch the soil. Its gray-green leaves stay on the plant through winter. Greenish-white flowers appear from September to October. The flowers and fruit add interest, and birds spread the seeds.

Grow this ivy in part shade or full shade. It accepts many soils but prefers rich, evenly moist loam. It can also cope with some drought. Missouri Botanical Garden lists USDA zones 7–10 for the plant. Its growing notes also report survival in zone 6. Chicago Botanic Garden lists zones 7–9. A sheltered, shady site helps at the colder end. This limits exposure to winter wind, cold, and full sun. Seeds, cuttings, and layering offer ways to raise new plants.

Use it to cover fences, walls, or trellises in shade. It also serves as ground cover or a lawn substitute. On banks and slopes, its spreading growth helps hold soil. Ground cover needs little pruning unless it crosses its bounds. Trim edges with shears or a spade to limit spread. Watch climbing stems near buildings, where they can enter gutters. They can also harm paint, loose mortar, and aluminum siding.

Serious pest and disease problems are not usually reported. Mites can cause trouble, as can aphids and scale. Mealybugs, caterpillars, and loopers may also occur. Diseases include leaf spots, canker, stem rot, and powdery mildew. Plants For A Future lists no known edible uses. It records traditional medicinal uses for leaves, berries, and plant decoctions. These include use for skin complaints and to promote sweating or bowel movements. The supplied evidence does not establish this species' toxicity.
