Hibiscus (Hibicus rosa sinensis) are shrubs widely grown in Australian gardens for their flamboyant late spring to autumn flowers in colours of red, pink, orange, yellow, purple and white or in colourful combinations.
New flowers, which may be double or single, unfurl daily. These deciduous shrubs can be grown as a stand-alone feature plant, as an informal hedge, or as a container or courtyard plant. They are also suited to planting around a swimming pool.
There are many named varieties in sizes that range from under 1m to well over 3m in height. See a wide range of hibiscus varieties on show at summer flower garden shows or visit your hardware or garden centres for great advice on a variety to suit your garden. Here are a few to consider:
- Hibiscus syriacus This species flowers from spring to autumn in shades of white, mauve, pink or lavender. This variety will grow 3-6m high by 2-3m wide. It is also cold tolerant.
- Hibiscus tiliaceus This species flowers in the warmer months in shades of white or yellow. This variety grows to a large shrub (8m x 3-6m) so ensure you have the space in the garden. Ideal as a windbreak, it will also tolerate coastal conditions.
- Hibiscus moscheutos This species flowers from summer to autumn, in shades for white, pink or red. This smaller variety growing to 2.4 m high by 1mn it is ideal for borders or containers.
- Hibiscus schizopetalus The species flowers from spring to autumn, in shades of red, white or pink. The Japanese lantern style flowers are very bird attracting.
Aspect Hibiscus thrive in full sun positions but prefer shelter from strong winds. Even though they are winter deciduous, they need frost protection.
Soil All grow best in a rich, well-drained soil so dig in added organic matter and/or add in Seasol Super Compost to prepare for planting.
Climate Hibiscus grow in most area except the very cold climates as they are not frost tolerant. In areas with hot summers but cold winters, grow hibiscus in large containers and move them into a sunny, frost-free position during winter.
