General Description:

Isopogon is a genus of around 35 species, all occurring only in Australia. They are found in the southern half of the continent in temperate regions. Most are small to medium sized shrubs having flower clusters arranged in globular heads. The fruits are also globular in shape giving rise to the common name of “drumsticks”. Some are also called “coneflowers” although this name is more usual in the related genus Petrophile.

Isopogon petiolaris is a low, spreading shrub usually less than 1 metre high. The leaves are 100-150 mm long and are divided into many linear segments each having a sharp tip. The leaf stalk may be about half to two-thirds of the total length of the leaf. Yellow flowers occur in spring and summer, conspicuously displayed on the ends of the branches. The flower clusters are around 35 mm in diameter and are followed by the spherical (barrel-shaped) seed pods which remain on the plant for an indefinite period.

This is an attractive and hardy plant but it is not widely cultivated. It requires a well drained position in full sun or light shade.

I.petiolaris is usually propagated from seed which germinates readily without pretreatment. Propagation from cuttings should also be successful.

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*
