General Description:

Hibiscus is a genus which is well known in horticulture through the many exotic species and cultivars, principally Hibiscus rosa-sinensis which has thousands of registered cultivars. Overall there are more than 300 Hibiscus species which occur mainly in tropical and sub-tropical regions. Australia has about 40 native species, most of which are endemic. There are also a number of closely related genera in Australia with Hibiscus-like flowers. These include Abelmoschus, Alyogyne, Gossypium, Howittia and Lagunaria.

Hibiscus pentaphyllus is a small shrubby annual to about 1.5 metres high by a similar width. The leaves are up to 70 mm long by 50 mm wide and deeply lobed. The flowers are bright yellow with a central maroon or brown blotch. They are about 75 mm in diameter of typical hibiscus shape.

In common with most Hibiscus species, the individual flowers last only 1-2 days but new flowers continue to open over a long period, generally in summer and autumn. The flowers are followed by hairy seed capsules containing a number of seeds.

Hibiscus pentaphyllus is not in widespread cultivation but it has potential as a colourful annual for tropical and sub-tropical areas. It should perform best is a sunny position with well drained soils.

In common with the exotic hibiscus cultivars, hibiscus beetles may be a problem. These can be controlled by placing white ice cream containers with detergent water among the hibiscus plants and putting fresh water and detergent in the containers every few days.

Propagation from seed is relatively easy and no special pretreatment is needed although germination will be faster if seed is abraded or soaked before planting. Cuttings should also strike readily.


For further information on Australian Malvaceae, see the Australian Native Hibiscus and Hibiscus-like Species website.

Thanks to Jim Purdie for the hint on using detergent water to trap hibiscus beetles.

Search Tips

By default the search engine tries to locate pages which have exact matches for all of the words entered in your search query. If that fails, it then tries to locate pages which contain any words in your search query. If that happens a short message is displayed at the top of the search results indicating this has been done. In addition, there are several ways to modify the default search behavior.  Note, searches are case insensitive.

Phrase Search
The search engine supports three types of phrase search.

  • To match an exact phrase, use quotes around the phrase. Example: "banksia integrifolia"
  • To match a near (within a couple of words) phrase, use square brackets [around the words]. Example: [banksia integrifolia]
  • To match a far (within several words) phrase, use braces { around the words }. Example: {banksia integrifolia}

+ and - qualifiers
If you prepend a word with + that word is required to be on the page. If you prepend a word with - that word is required to not be on the page. Example: +always -never

* Wildcard
If a query word ends with a * all words on a page which start the same way as that query word will match. Example: gift*

? Wildcard
If a query word contains a ? any character will match that position. Example: b?g

Boolean Search
You can use the following boolean operators in your search: AND, OR, NOT. These operators MUST be in capital letters. Example: (contact AND us) OR (about AND us)

All of these techniques can be combined: +alway* -ne??r*
