General Description:

Banksia robur is a small to medium shrub, 2 to 3m high and wide. The large leaves are stiff, leathery, egg-shaped, broadest at the tip, shiny above, dull beneath, margins toothed, 10-30cm x 6-10cm.

Heads of blue-green flower buds arise from the junctions of branches and form into dense greenish-yellow flower heads 6-15cm in length, changing to dull orange and brown with age. This species can flower from seed in 3 years and flowers can occur at any time of year but are most commonly seen in winter or early spring. Seeds are held in hairy, woody follicles which are retained on the plant for a considerable period.

The species will tolerate poor soils and poor drainage and has been used as a rootstock for less hardy species. It naturally occurs in wet areas (hence the common name) on sandy soils and appreciates extra water, especially when actively growing and during dry spells.

Propagation from seed is reliable.

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*
