Willow Wattle

Acacia Salicina

Appearance

Erect shrub or tree 3-10m in height, but can grow up to 20m.

Phyllodes (flattened leaf stems) are narrow (5-12mm wide) and 5-17cm long. They have a prominent central vein and a curved pointed tip.

Flowers are pale yellow or white, and clustered in groups of 15-30 in inflorescences. Flowers form globular balls

Seed pods are straight or slightly curved, and measure 3-12cm in length. Seeds are bright red or orange.

 

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 usually occurs February-June

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

 

Where To Look

Grows in dry sclerophyll forest, shrub-land and woodland of inland regions, mostly along river banks and creeks.

Common in most states, except WA and TAS.

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

    Similar to the Small Cooba (A. ligulata) but distinguished most readily from that species by its pendulous, thicker (coarsely wrinkled when dry) phyllodes with a non-hardened mucro (apical point), and its cream to pale yellow heads, whereas Small Cooba has deep golden flowers. In addition, the phyllodes of A. salicina are often broader (4–30 mm cf. 4–14 mm wide).
