Hibbertia stellaris

It naturally grows in swamps; despite this, it is extremely sensitive to phytophthora and needs to be grown in well-drained soil in cultivation.

[1] Austrian botanist Stephan Endlicher described Hibbertia stellaris in his 1837 work Enumeratio plantarum quas in Novae Hollandiae ora austro-occidentali ad fluvium Cygnorum et in sinu Regis Georgii collegit Carolus Liber Baro de Hügel, from a specimen collected near the Swan River.

[1] Meanwhile, German botanist Ernst Gottlieb von Steudel described Hibbertia tenuiramea in the 1845 work Plantae Preissianae, from a specimen collected near Perth.

It generally succumbs within 18 months of planting in the ground, although it lives longer in containers such as pots or hanging baskets.

[7] Plants in full sun (as opposed to in part-shade) flower more profusely but tend to be shorter-lived.
