Overview

Amyema miquelii is an evergreen aerial mistletoe native to eastern and southern Australia, living as a partial parasite on the branches of eucalypts, especially boxes and ironbarks, and sometimes wattles. Rather than rooting in the ground, it attaches to a host branch by a swollen union and draws water and minerals from it while making its own sugars. It forms a pendulous, clumped shrub roughly 1.5-6.5 feet (0.5-2 m) across, with drooping, narrow, grey-green leathery leaves that closely resemble the foliage of its eucalypt host. In summer and autumn it carries clusters of curved, tubular flowers in red, often tipped with green or yellow, grouped in threes and rich in nectar. Honeyeaters feed on and pollinate the flowers, and the small red to pink berries that follow are eaten by the mistletoebird, which spreads the sticky seeds to new branches. Heavy infestations can stress or kill individual host limbs, though the plant is a natural part of woodland ecology and supports many birds and insects. It cannot be grown in soil and depends entirely on a living host.

Native Range

Native to eastern and southern mainland Australia, across Queensland, New South Wales, Victoria, and South Australia. It grows in eucalypt woodland and open forest, on the branches of host trees rather than in the soil.

Suggested Uses

Amyema miquelii features in woodland and habitat conservation rather than as a planted garden subject, because it supports honeyeaters, the mistletoebird, and several butterflies whose larvae feed on its leaves. In natural and revegetated woodland it adds nectar, fruit, and shelter through the year. It is studied as an example of host-parasite and bird-plant relationships.

How to Identify

Recognised as a pendulous clump of drooping, grey-green, leathery leaves hanging from the branch of a eucalypt or wattle, often blending with the host foliage. Its red, curved, tubular flowers are grouped in threes, unlike many mistletoes whose flowers are paired. The swollen attachment point where it joins the host branch is a further clue.

Summer Fall

Clusters of red, tubular, nectar-filled flowers open mainly in summer and autumn, grouped in threes along the stems. The flowers are pollinated by honeyeaters drawn to the nectar. Small red to pink berries follow and ripen over the following months.

Care & Maintenance

Care Guide

Amyema miquelii is a parasitic plant and is not cultivated in the usual sense, as it cannot grow in soil or a pot. It establishes only when a mistletoebird wipes a sticky seed onto a suitable host branch, where the seed germinates and taps into the host. Its health depends entirely on the vigour of its host tree, and it shares the host exposure to sun, drought, and frost. In gardens and parks it appears on its own in established eucalypts rather than being planted. Where a single tree carries many mistletoes, the extra demand can weaken or kill affected branches. Removal, if wanted, means cutting out the attached section of host branch.

Pruning

Pruning is not a normal part of growing this plant, since it is a parasite that arrives on its own. Where a mistletoe is unwanted, the host branch is cut back beyond the point of attachment, as the mistletoe regrows if any of its tissue remains. Otherwise it is left in place as habitat.
