Summer-flowering shrub for warm temperate and tropical climates.
Many species (mostly evergreen) and hundreds of named cultivates.
Magnificent large flowers (some to 20cm) range in colour from
white through yellow, orange, pink, red and maroon. Flowering
period is November to April.
Foliage consists of smooth dark green ovate leaves with toothed
margins. There are evergreen as well as deciduous hibiscus,
but those found in nurseries are usually evergreens due to the
many magnificent hybrids that are sought after by gardeners.
Sizes vary, some can reach 4 meters in height and more.
They tolerate somewhat salty air.
Growing
Sunny sheltered position. All species are susceptible to frost
which can completely defoliate them. Pick a site with care as
hibiscus have vigorous root systems and dislike being moved.
The soil should be rich, well drained and preferably slightly
acidic. Do not plant in heavy clay.
Prune in early spring (to any shape desired) and follow up
with complete fertiliser.
Make sure to mulch in the dry summer months to retain moisture.
Some varieties adapt to dry conditions and partial shade. H.
heterophyllus and 'Apple Blossom' are two of them.
