General Description:

Grevillea treueriana is a small shrub of open habit to 1-1.5 metres high by a similar width. Leaves are 25-30 mm long with recurved margins. They are deeply divided into stiff, linear lobes with sharp, pungent points. The “toothbrush”-shaped flower clusters are bright orange red and tend to hang downwards from the ends of the branches. Flowering occurs in winter though to spring.

This species has not been widely cultivated but is now becoming more readily available through specialist native plant nurseries. It is best suited to areas with a dry summer climate and it may prove more difficult in humid, wet summer districts such as coastal New South Wales and Queensland. In those areas grafting onto a hardy rootstock may be necessary for long term growth. It should be grown in a warm, sunny location in well drained soils. It is tolerent of at least moderate frosts. Like most grevilleas, the flowers attract honey-eating birds.

The species can be grown from seed which should be “nicked” with a sharp knife prior to sowing to improve germination. Cuttings from firm, current season’s growth can be slow to strike and success is improved by using a root promoting hormone. The species has been successfully grafted to hardy root stocks such as G.robusta and G.”Poorinda Royal Mantle”.

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*
