Eremophila longifolia aka Emubush

Eremophila longifolia is an Australian shrub or small tree. It belongs to the Scrophulariaceae family. Its native range covers much of mainland Australia. Records include Western Australia, South Australia, and the Northern Territory. It also grows in Queensland, New South Wales, and Victoria. Kew places it in desert and dry shrubland habitats. Plants For A Future notes inland sites, often on limestone. These records place it across a broad inland range.

The plant can reach about 20 feet [6 metres] tall. Its shrub or tree form matters when choosing a site. It needs space for a woody plant of that height. The supplied accounts do not give its mature width. They also lack details of its bark and leaves. No flower colour or flowering season appears in these accounts. The flowers have both male and female organs. The evidence does not describe the fruit or identify pollinators.

For cultivation, Plants For A Future lists sun or light shade. It suggests woodland edges and sites with dappled shade. The plant can grow in sand, loam, or clay. Its stated soil range includes mildly acid through mildly alkaline conditions. That range gives gardeners scope across several soil types. The same source says it prefers moist soil. This differs from the dry habitats noted in its native range. Native habitat alone does not settle its garden watering needs.

Plants For A Future reports hardiness near 19°F [−7°C] in Australian gardens. This is a temperature report, not a stated hardiness zone. The source lists seed as a means of propagation. It provides no further steps for raising young plants. Its listed garden settings include sunny woodland edges and light shade. It reports no weed potential for this species. The supplied evidence names no pests or diseases.

The wood has uses in veneers, inlay, and cabinet work. It is hard, dense-grained, and durable, but also brittle. These traits can make it difficult to work. Plants For A Future records medicinal use for sores and colds. This record does not establish safe treatment or dosage. The same source calls the plant toxic and lists no edible uses. It should not be treated as a food plant.
