General Description:

Hardenbergia is a small genus of three species, the most common and best known of which is Hardenbergia violacea.

Hardenbergia violacea is usually a climbing plant whose branches twist around the stems of other plants. It is moderately vigorous but rarely covers other plants so extensively as to cause damage. Shrubby forms without any climbing tendency are known. The leaves are dark, glossy green with prominent veins and are 75-100 mm in length.

The flowers, which appear in winter and spring, are usually violet in colour but pink, white and other colours are sometimes found. The flowers are the typical “pea” shape consisting of 4 petals; the “standard”, the “keel” and two “wings” as shown in the diagram.

A number of colour variants of H.violacea are becoming generally available in nurseries, with some imaginative cultivar names attached – for example:

  • “Happy Wanderer” (very vigorous, purple flowers)
  • “Pink Fizz” (pink flowers – climbing, not vigorous)
  • “Mini Haha” (compact, shrubby – purple flowers)
  • “Alba” (white flowers)
  • “Free ‘n’ Easy” (whitish flowers, vigorous climber)
  • “Blushing Princess” (shrubby – mauve-pink flowers)
  • “Purple Falls” (trailing – purple flowers, good for rockeries)
  • “Bushy Blue” (shrubby – blue-purple flowers).

H.violacea is a popular and generally hardy garden plant which is widely grown. It is adaptable to most soils and aspects although sunnier positions will usually result in better flowering. Given the wide range of the species, however, forms from drier areas may not be vigorous in tropical areas, and vice versa. Where possible, it is best to select forms from similar climatic zones to the area where they are to be cultivated.

Propagation is easy from seed following pre-treatment to break the physical dormancy provided by the impervious seed coat. Pre-treatment can be carried out by abrasion or by the use of boiling water (further details can be found in under the “Propagation” tab of the “Pea Family” page). The seed retains viability for many years. Cuttings strike well using 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*
