Growing Hibbertia Plants In Your Garden
Hibbertia, also known as Guinea flower and climbing Guinea plant, is a genus of about 115 different species of perennial shrubs and trailing or climbing plants in the Dilleniaceae family. The vast majority of these plants are native to Australia, but some species are found in the Pacific Islands and Madagascar. These generally disease- and pest-resistant plants are a favorite of gardeners in warm climates. Plants in this genus produce flowers in only two colors: yellow and orange. One species in this genus is in jeopardy of becoming extinct. A total of 111 species of Hibbertia are various shades of yellow. The remaining four species are various shades of orange. All species produce five-petaled flowers from early spring to late summer, depending on location.
During flowering, the evergreen foliage is almost completely covered by the plant’s abundant flowers. Plants typically grow from 18 to 36 inches (45-90 cm) tall and can be up to 138 inches (350 cm) across. These heat-loving plants need to be situated in a sunny or partially shady location. Plants in dimmer light have a more compact habit but will grow more slowly than those in full sun. There are few pests or problems with the guinea flower. It is tolerant of short periods of drought and will usually survive a light frost.
