General Description:

Senecio is a very large cosmopolitan genus of about 1500 species with about 50 species native to Australia. A number of exotic species have become serious weeds in parts of Australia (eg. Senecio madagascariensis. “Fireweed”, a serious pest of pastures in eastern Australia). They may be annuals or perennials usually having flowerheads comprised of a central cluster of small flowers surrounded by radiating petal-like flowers.

Senecio magnificus is an erect shrub to about 1 metre high with soft, grey leaves about 80 mm long. The flower heads are large and very conspicuous. Flowering occurs mainly in spring but occasional flowers may be seen at other times.

Like most of the Australian members of the genus, S.magnificus is not often cultivated. It deserves greater attention from gardeners as its grey foliage and bright yellow flowers are eye-catching. It should be suited to a sunny position in gardens in dry climates but may be difficult to maintain in wetter areas. Plants may become “leggy” with age and should be trimmed annually.

Propagation from seed has proven to be difficult. Cuttings of firm, current season’s growth should strike with reasonable success.

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*
