Orchids, lilies and some of the later “eggs and bacon” shrubs are now in flower wherever native plants survive. They are almost certainly accompanied by a good supply of guinea-flowers. The good supply is due to the fact that rabbits do not fancy eating them . The variety of species observed is an indicator to the quality of remnant bushland , if little is seen expect guinea flowers , it is a sign that rabbits have been bad in the area.

Guinea flowers are small woody plants , all recognised easily by their regular , bright yellow flowers of five spreading petals . They flower for a long time and are open even on dull cold days .  

One nationally threatened species of Guinea- flower grows in our area.  The Euroa Guinea-flower is listed under the Flora and Fauna Guarantee Act 1989 and as  ‘vulnerable’ by the DSE Advisory List.

The Euroa Guinea- flower   –  Hibbertia humifusa  subsp. erigens.ssp.

Habitat : This  plant is found most commonly in Grassy Woodlands with one or more of the following   overstorey trees: Red Box, Red Stringybark, Blakely’s Red Gum .
It is largely known from disturbed areas including roadsides. Soils are shallow sandy loams to gravelly clay loams and the topography is low  granitic hills to plains. Now protected, its numbers are increasing and many healthy plants can be seen growing along the Hume Freeway from Euroa to Avenel. The Euroa Arboretum has a naturally occurring population.

Euroa Guinea- Flower

Distribution :The current distribution of the Euroa Guinea-flower is confined to the Euroa, Avenel,Longwood,Warrenbayne and Barjarg areas. Prior to white settlement it is thought to have occurred much more widely.

Fragmentation:
Many populations are small and highly fragmented (genetic diversity may be limited in these instances). Small populations are also vulnerable to local extinction through single
episodic events such as severe bushfire.

More common local Guinea- Flowers include the Grey Guinea – flower Hibbertia obtusifolia , the Erect Guinea-flower  Hibbertia riparia, and the Silky Guinea-flower Hibbertia sericea.
