Overview

Viscum album is an evergreen, hemiparasitic shrub in the family Santalaceae that grows on the branches of trees rather than in the ground, forming rounded clumps 12-39 inches (30-100 cm) across. Its repeatedly forking green stems carry paired, leathery, untoothed leaves 1-3 inches (2.5-8 cm) long, yellow-green and tongue-shaped, that stay on the plant year-round. Tiny, four-parted green flowers open from February to April, with male and female flowers on separate plants. Fertilised female plants ripen sticky white berries 0.2-0.4 inch (6-10 mm) wide through autumn and winter, each holding a seed in glue-like pulp that birds spread to new branches. The plant taps into a host tree through a root-like haustorium, drawing water and minerals while making its own sugars. The species grows across Europe and into western Asia on apple, poplar, lime, hawthorn, and many other broadleaved hosts. All parts, especially the berries, are poisonous to people if eaten, and a heavy infestation can weaken or deform host branches, so it is both gathered at Christmas and managed as a pest in orchards.

Native Range

Native across Europe and into western Asia, from Britain and southern Scandinavia south to the Mediterranean and east to the Caucasus. It lives on the branches of broadleaved trees, especially cultivated apple, poplar, lime, hawthorn, and maple, in orchards, parkland, gardens, and open woodland.

Suggested Uses

Grown as a curiosity and for seasonal greenery, established on garden apple and lime trees for winter berries and Christmas use. It supports specialised insects and is eaten by birds such as the mistle thrush, which spread its seed. In orchards and amenity trees it is also controlled to limit damage to the host.

How to Identify

A rounded, evergreen clump perched on a tree branch, with green, repeatedly forking stems and paired, leathery, yellow-green tongue-shaped leaves. In winter the bare host tree makes the green ball of mistletoe easy to spot, and female plants carry pearly white, sticky berries in pairs or threes. No other plant in its range combines this branch-dwelling habit, regular forked branching, and translucent white berries.

Winter Spring

The small green flowers open from February to April, before most host trees leaf out, with male and female flowers borne on separate plants. They are pollinated by insects and wind and are easy to overlook. On female plants the white berries ripen from October onward and persist through winter.

Care & Maintenance

Care Guide

Viscum album cannot be grown in soil; it is established by pressing ripe berry seeds onto the bark of a suitable host branch, usually apple, lime, poplar, or hawthorn, in late winter. Germination is slow and only a small fraction of seeds take hold, often taking several years to form a visible plant. Once attached it needs no care, drawing water and minerals from the host while photosynthesising through its evergreen stems. A vigorous host in an open, sunny position supports the strongest growth. Heavy colonisation can stunt or kill host branches, so growth is sometimes thinned in orchards and amenity trees. Both male and female plants are needed for berries to form.

Pruning

On the mistletoe itself no pruning is needed. Where it overloads a host, whole clumps are cut out with a margin of host wood in winter, since fragments left on the branch regrow. Female plants are often cut for seasonal decoration, which also keeps their spread in check.
