Overview

Muellerina eucalyptoides is an evergreen aerial hemiparasite in the family Loranthaceae that grows on the branches of eucalypts and related trees, drawing water and minerals from the host through specialised attachments. It forms pendulous, trailing stems 1.5-6 feet (0.5-1.8 m) long that hang from the host branch. The narrow, leathery leaves are 1-3 inches (2.5-8 cm) long, grey-green, and often curved, resembling the foliage of the eucalypt host. Small tubular flowers in green to reddish tones, about 0.4-0.6 inch (10-15 mm) long, appear in clusters along the stems, followed by small oval berries that birds eat and spread. The plant produces its own chlorophyll but depends on a living host for water, and heavy infestations can weaken or kill host branches. It establishes where birds deposit seed onto suitable host bark, mainly on Eucalyptus spp. and Angophora spp..

Native Range

Native to eastern and southeastern Australia, across Queensland, New South Wales, Victoria, and South Australia. Occurs in open forest and woodland wherever suitable eucalypt hosts grow, from the coast to inland ranges.

Suggested Uses

Not cultivated as a garden plant, as it grows only on living host trees. In natural woodland and on host eucalypts it contributes berries and shelter used by birds and insects. Its presence is managed on host trees in parks and gardens where branch loss is a concern.

How to Identify

Recognised by pendulous, trailing stems 1.5-6 feet (0.5-1.8 m) long hanging from the branches of a host tree, with narrow grey-green curved leaves resembling eucalypt foliage. Small green-to-reddish tubular flowers 0.4-0.6 inch (10-15 mm) long and small oval berries appear along the stems. The drooping habit and attachment to a host branch separate it from the host's own foliage.

Summer Fall

Tubular flowers appear mainly in summer and autumn, from December to May in its native range, varying with location and host. Flowering and fruiting can overlap, and berries ripen over several months. Birds feeding on the berries spread the seed to new host branches.

Care & Maintenance

Care Guide

Grows only as a parasite on the branches of living eucalypts and related trees and cannot be grown in soil. Establishment depends on birds depositing the sticky seed onto host bark, where it germinates and attaches. The plant makes its own sugars through green leaves but relies on the host for water and minerals. Heavy infestations draw down host vigour and can kill individual branches, especially on stressed or isolated trees. It forms part of native woodland food webs, with berries and foliage eaten by birds and insects. Control on host trees involves removing affected branches below the attachment point.

Pruning

On host trees, mistletoe is reduced by cutting off the infested branch well below the point of attachment, as the parasite regrows from tissue embedded in the wood. Light infestations are sometimes left in place as part of woodland habitat. The plant cannot be pruned in the way a free-standing shrub is.
