Alpine Baeckea

Baeckea gunniana

Appearance

Description: densely branched shrub with a tea-tree aroma when crushed. Usually grows between 0.5-1 m in height. May reach 2m tall in lower altitudes. Will usually grow along the ground or against rocks. 

Leaves: usually crowded, oblong, and do not spread very widely. Size approximately 2–4 mm long and 1 mm wide, thick, concavo-convex (concave on both sides) and pointed at ends.

Flowers: solitary, white and have circular petals, 8 mm across. Usually appear between December and April.

Fruits/seeds: cuplike with angular seeds. Fruits grow to approximately 2 mm in diameter. 

What to Observe

  • First fully open single flower
  • Full flowering (record all days)
  • End of flowering (when 95% of the flowers have faded)
  • Open seed pods containing 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. Climate change will directly affect the ecological communities in which this alpine species resides. An increase in temperature and extreme heat events will reduce viable habitat for this species.

Help scientists answer the question: "How are our animals, plants and ecosystems responding to climate change?"

When To Look

Year-round. Flowers appear between December and April. 

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

Where To Look

Baeckea gunniana occurs in alpine and sub-alpine sites. It is generally found in heath and sedge-lands in wet rocky sites or bogs, above 1000 metres altitude in southeast mainland Australia and Tasmania. 

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

  1. What Else?

    Mountain Baeckea (Baeckea utilis): branches of this plant are far more wiry and slender. Leaves spread much wider than that of Baeckea gunniana, are flat on their surface and keeled below. Flowers are also slightly smaller (to 6 mm across) whereas B. gunniana flowers are 8 mm across. 

     

     

  1. Did You Know?

    The leaves emit a powerful camphor-like scent when handled.
