General Description:

G.wilkinsonii was first discovered in 1991 along the banks of the Goobarragandra River near Tumut in NSW. It is a shrub 1.5 to 2 metres high x 2 metres wide with oblong, toothed leaves which can be up to 170 mm long by 25 mm wide. The mauve to purple flowers are typical of the “toothbrush”-flowered grevilleas where the individual flowers are arranged in a terminal one-sided raceme. Flowers occur during winter and spring.

This species has only been in cultivation for a short period but appears to be hardy and reliable in temperate climates of the east coast. It prefers well drained soils in a sunny position. The species is performing exceptionally well at the National Botanic Gardens in Canberra and should become a very popular species when plants become more widely available. Like most grevilleas, the flowers attract honey-eating birds.

Because of its rarity, seed is not available but would probably germinate well if “nicked” with a sharp knife prior to sowing. Limited experience indicates that cuttings from firm, current season’s growth strike reliably.

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*
