Native Buttercup

Hibbertia hypericoides

Appearance

  • Erect spreading dark green shrub.
  • Size: 0.2 – 1 m high.
  • Leaves: long, narrow, oblong, blunt, dark green above with very recurved margins.
  • Flowers: Stalked, yellow flowers with 5 distinct petals. The stamens are all found on one side of the centre of the flower and look like a tiny hand of bananas.
  • Fruit/seed: rarely seen.

What to Observe

  • First fully open single flower
  • Full flowering (record all days)
  • End of flowering (when 95% of the flowers have faded)

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.

When To Look

  • Shrub is found all year round.
  • Flowering from April to December

Where To Look

  • South Western Australia.
  • Ranging from Kalbarri National Park, south to Albany and inland to Dryandra.
  • Common in many urban bushlands around Perth.

Sightings

The map below displays the accumulated observations of these species as reported by ClimateWatch observers, together with the layer showing how the range of the species might change between now and 2085, with orange areas indicating where the species might disappear, and green areas where the species range might expand.

  1. What Else?

    There are many species of Hibbertia. Other species have differently shaped leaves (often sharply pointed) and stamens all around the centre of the flower

  1. Did You Know?

    Flowers are cross pollinated by beetles.  This is also known as Cantharophily
