Weeping Emu Bush
Eremophila longifolia
The Weeping Emu Bush (Eremophila maculata) is a striking Australian native shrub belonging to the family Scrophulariaceae (recently reclassified into Phrymaceae by some taxonomies). It is one of the most widely cultivated species in the genus Eremophila, prized for its gracefully arching branches, tubular flowers, and remarkable drought tolerance.
• The genus name Eremophila derives from Greek: "eremos" (desert) and "philos" (loving) — literally "desert-loving"
• The specific epithet "maculata" means "spotted," referring to the often-spotted throat of the flowers
• Commonly known as the Spotted Emu Bush or Weeping Emu Bush due to its pendulous growth habit
• One of the hardiest and most adaptable Australian native shrubs in cultivation
Taxonomy
• Native range spans multiple Australian states: Queensland, New South Wales, Victoria, and South Australia
• Found across diverse inland and semi-arid regions of the continent
• The genus Eremophila comprises over 200 species, almost all endemic to Australia
• Australia's arid and semi-arid zones are the center of diversity for the genus
The emu bush common name is thought to derive from the belief that emus (Dromaius novaehollandiae) feed on the fruits of Eremophila species, though direct evidence of this dietary preference is limited.
Stems & Branches:
• Branches are slender, pendulous, and often arching gracefully to the ground
• Young stems may be slightly sticky (viscid) due to resinous secretions
• Bark becomes rough and darker with age
Leaves:
• Arranged alternately along the stems
• Linear to narrow-lanceolate, typically 1.5–5 cm long and 2–6 mm wide
• Margins are entire (smooth-edged)
• Color ranges from bright green to grey-green; surface may be slightly hairy or glabrous depending on variety
• Some forms have resinous or sticky foliage
Flowers:
• Tubular, approximately 2–3 cm long, borne singly or in small clusters in leaf axils
• Color varies widely by cultivar and variety: pink, red, orange, yellow, cream, or spotted combinations
• Interior of the floral tube is frequently spotted or blotched with darker markings
• Five-lobed corolla with two upper lobes and three lower lobes
• Flowers attract nectar-feeding birds such as honeyeaters
Fruit:
• Small, dry, ovoid drupe approximately 4–6 mm long
• Contains a single hard seed
• Fruits mature and release seeds in response to environmental triggers such as rainfall
Habitat:
• Open woodlands, grasslands, and semi-arid scrublands
• Often found along dry creek beds, floodplains, and rocky outcrops
• Tolerates a wide range of soil types including clay, loam, sand, and gravelly substrates
Drought Adaptations:
• Deep and extensive root system capable of accessing subsoil moisture
• Resinous leaf coatings reduce water loss through transpiration
• Can survive extended periods of severe drought by shedding leaves and entering dormancy
• Rapidly responds to rainfall events with new growth and flowering
Pollination:
• Primarily pollinated by birds (ornithophily), especially honeyeaters of the family Meliphagidae
• Tubular, brightly colored flowers are classic adaptations to bird pollination
• Nectar-rich flowers provide an important food source in arid ecosystems
Fire Ecology:
• Some Eremophila species can regenerate from root suckers or lignotubers after fire
• E. maculata may resprout from the base following low-intensity fire events
Light:
• Full sun is ideal for maximum flowering and compact growth
• Tolerates partial shade but flowering may be reduced
Soil:
• Adapts to a wide range of soil types: sandy, loamy, clay, and rocky
• Must have excellent drainage — waterlogged soils are the primary cause of failure in cultivation
• Tolerates alkaline, neutral, and slightly acidic pH
• Does not require fertile soil; performs well in poor, nutrient-deficient substrates
Watering:
• Extremely drought-tolerant once established
• Water regularly during the first growing season to establish roots
• Once established, requires little to no supplemental irrigation
• Overwatering is the most common cause of death in garden settings
Temperature:
• Tolerates extreme heat (above 40°C) and moderate frost (down to approximately -5°C to -7°C depending on provenance)
• Suitable for USDA hardiness zones 8–11
Pruning:
• Responds well to light pruning after flowering to maintain shape and encourage bushier growth
• Can be pruned hard if renovation is needed
Propagation:
• Easily propagated from semi-hardwood cuttings taken in late summer to autumn
• Cuttings root readily without hormone treatment in many cases
• Can also be grown from seed, though cultivars may not come true from seed
Common Problems:
• Root rot (Phytophthora) in poorly drained soils
• Branch dieback in humid climates with poor air circulation
• Generally pest-resistant; occasionally affected by scale insects
Fun Fact
The Weeping Emu Bush is a masterclass in desert survival engineering: • Its resinous leaf coating acts as a natural "sunscreen" and moisture sealant, reducing water loss by up to 50% compared to non-resinous desert shrubs • A single established plant can survive on as little as 200 mm of annual rainfall — less than most cacti require The genus Eremophila is almost entirely endemic to Australia, making it one of the most uniquely Australian plant groups on Earth: • Of the 200+ known species, fewer than five occur naturally outside Australia • This extraordinary endemism reflects Australia's long geographic isolation and the evolution of its arid interior over millions of years Aboriginal Australians have used various Eremophila species for millennia: • Leaves and bark were used in traditional medicine for treating colds, skin infections, and inflammation • Some species were used in ceremonial smoking rituals ("smoking ceremonies") • The sticky resin was occasionally used as an adhesive Bird Magnet: • A single flowering E. maculata bush can attract dozens of honeyeaters and other nectar-feeding birds daily • In urban gardens, it serves as a critical food source for native birds, especially during dry periods when other nectar sources are scarce • The tubular flower shape has co-evolved with the curved bills of honeyeaters, ensuring efficient pollen transfer
