Hibbertia aspera, the Rough Guinea Flower, is usually a bushy, dwarf to medium shrub or spreading climber that may spread by suckers.
The stems and leaves are wiry and roughened. Leaves are up to 25 millimetres long, 10 millimetres wide, elliptical, light to deep green with a rough surface (hence the common name).
The bright yellow flowers are about one centimetre across with spring and early summer the main flowering period. Flowers are small but what they lack in size they make up for in quantity. During the flowering period the branches are covered with cheerful blooms.
H. aspera occurs in all eastern states including Tasmania as well as South Australia.
More by good luck that management we planted a specimen near one of the supports of our patio roof together with Clematis and Pandorea climbers. The Rough Guinea Flower took advantage of the situation and using the other plants for support became a dense climber that becomes a blaze of colour during the lengthy flowering period. H. aspera, together with the other climbers, is providing safe nesting sites for native birds.
Propagate from root suckers or stem cuttings.
The species name means roughened and refers to the stems and leaves.
The Hibbertias or Guinea Flowers are common throughout the Australian bush. There are about 115 species and 110 of these are endemic. They have colourful yellow flowers but unfortunately not many species are in cultivation.
