Spreading Emu-bush

Eremophila divaricata subsp. divaricata

Appearance

Description: A spreading shrub with stiff, tangled branches often ending in sharp spines. 

Size: Grows to a height of 0.5-1.5m tall and a width of up to 2m. 

Leaves: Leaves are arranged alternately along branches. They are erect, linear to oblong in shape and are generally 5-20mm long. They are smooth and without hairs and are mid-green in colour. 

Flowers: 3.5–6.5 mm long, 0.8–2 mm wide, mauve to lilac-coloured, bell-shaped, spotted, found solitary at the bases of the leaves. The flower's 4 stamens (pollen-bearing) are fully enclosed in the petal tube.

Fruits/seeds: Fruit ovoid to conical, 5–9 mm long, 2–4.5 mm diam., dry, woody, beaked and splitting into 4 segments at apex.

What to Observe

  • First fully open single flower 
  • Full flowering (record all days)
  • End of flowering (when 95% of the flowers have faded)
  • No flowering
  • Fruits/seeds (record all days)

ClimateWatch Science Advisor

We expect plants to start shooting and flowering earlier in the year as a result of climate change warming the Earth. They may also start appearing in new areas, as warmer temperatures enable them to live in environments that were previously too cold for them. Help scientists answer the question: "How are our animals, plants and ecosystems responding to climate change?"

When To Look

Flowering occurs from September to April (mostly from November) and is followed by fruiting. 

Note: ClimateWatch is looking for any changes in the timing of these events so remember to keep a lookout all year!



Where To Look

Spreading emu-bush occurs mainly in River Red Gum and Black Box communities on heavy clay soils of riverflood plains. 

Note: ClimateWatch is looking for any changes outside of their known ranges so remember to keep a lookout beyond these regions too!

    Has medium pink-lilac flowers spotted with purple on the lower lobe, as opposed to Spotted Emu Bush (E. maculata) which has flowers with or without spots. It's stamens (pollen-bearing anthers) are fully enclosed in the petal tube whereas they extend outside of the tube in E. maculata
