General Description:

The genus Olearia is found in Australia, New Zealand and New Guinea and has about 130 species native to Australia. They are generally small to medium shrubs commonly known as “daisy bushes”.

Olearia stellulata is usually a small to medium shrub up to 2-3 metres high by a similar width. The leaves are typically oblong to elliptical in shape, 90-150 mm long and may have entire or toothed margins. The under surface of the leaves is densely covered with stellate hairs. The daisy flower heads are usually white but pink, purple or blue forms are known. Flowers appear in spring and summer and the flower heads are about 15-25 mm in diameter.

With a few exceptions, olearias are not commonly seen in cultivation. O.stellulata is not widely cultivated other than by enthusiasts. It is a hardy shrub for well drained, moist soils in full sun or semi shade but, like many species in the genus, it can become leggy and sparsely foliaged with age. Annual pruning after flowering is recommended to restore vigour. The species is tolerant of moderate frost but may be damaged by heavy frost. It is not especially tolerant of extended dry conditions. A cultivar known as ‘Olwyn Barnett’ has been selected for its pink/purple flowers

Propagation of O.stellulata may be carried out from seed but germination may be unreliable. Propagation from cuttings of current season’s growth is usually not difficult and this is the only method that should be used for the cultivar ‘Olwyn Barnett’.

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*
