General Description:

Golden wattle is Australia’s national floral emblem. It was unofficially recognised as the emblem before being officially proclaimed on 1 September 1988. It is a a shrub or small tree 5-8 metres high. Like most members of the genus, the mature plant does not have true leaves but has leaf-like flattened stems called phyllodes. In A.pycnantha the phyllodes are lance-shaped (often curved) and between 5 and 20 cm long. The bright yellow flowers occur in the axils of the phyllodes as 20 or more globular-shaped clusters. Flowering is mainly in late winter and spring.

Acacia pycnantha is popular in cultivation but is best suited to temperate areas. It is quick growing and will often flower in the second season after sowing. It is suited to a wide range of soil types, provided they are not waterlogged, and a position in full sun or light shade. The species is tolerant of at least moderate frosts and can be grown in coastal districts but is best away from front line exposure to salt spray.

The species has become an environmental weed in some places (eg. Western Australia, California and particularly South Africa where it is a serious pest). It has also naturalised in the NSW Tablelands and in Tasmania so care should be exercised in planting A.pycnantha in areas close to bushland.

Propagation is relatively easy by normal seed raising methods following pretreatment by soaking in boiling water or by scarification. Propagation from cuttings may be successful but is not often used.

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*
