General Description:

Scaevola is a genus of about 70 species, most of which occur in Western Australia. They are mostly small, herbaceous plants distinguished by their fan-shaped flowers.

Scaevola aemula is probably the most commonly grown species. Because of its wide range, a number of forms exist but, in cultivation, it is typically a sub-shrub to about 150mm high by a width of half a metre. The leaves are 10 to 50 mm long, oval or wedge shaped and sometimes toothed. Flowers are seen in spring and summer, are usually pink, mauve or purple (occasionally white) and 25-30 mm in diameter. In recent years a number of selected forms have appeared in the nursery trade with specific flower colour and/or growth habit.

This is a reasonably hardy to very hardy species in well drained, moist soils in temperate climates. However, some care in selection of forms is advisable because those native to semi arid areas may not grow well in areas of high rainfall, and vice-versa. A position in full sun or light shade is usually suitable and the species makes an excellent subject for a hanging basket.

Propagation is difficult from seed but cuttings strike very easily from firm, current season’s growth.

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*
