General Description:

Eucalyptus macrocarpa is a very distinctive species having a mallee-type habit of growth and spectacular red flowers. There are two recognised subspecies; subsp macrocarpa is the most common form and is a small mallee of up to 4 metres in height while subsp. elachantha has a restricted occurrence south east of Geraldton. The latter differs from the common form in having smaller leaves and lower stature.

The foliage of E.macrocarpa attracts almost as much attention as the flowers. The leaves are ovate-elliptical in shape, sessile, up to 12 cm long by 8 cm wide and silvery-grey in colour.

The large flowers may be 100 mm in diameter and are usually bright red but pink-red forms are known. Flowering occurs from early spring to mid summer. The “gumnuts” which follow the flowers are also an interesting feature of the tree. They are very large and have a powdery grey covering.

As a species native to relatively dry areas, E.macrocarpa is best suited to cultivation in climates which have a dry summer. It has been grown in sub tropical districts but cannot be regarded as reliable in those areas. It has been observed growing and flowering in western Sydney. The species develops a lignotuber and should respond to hard pruning to near ground level if rejuvenation is required.

Propagation is from seed which germinates readily.

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*
