Hardenbergia violacea (Native Wisteria)

Hardenbergia violacea mauve

I noticed this plant scrambling along a fence on one of the main roads in the town. This particular form of Hardenbergia also makes a great plant for a ground cover or draped down an embankment. It is a very hardy plant which is perennial and should be trimmed back to the new shoots after flowering. If seed is to be collected, it is a good idea to let a few sprays remain on the plant to set seed and mature and to be cut back later. Cuttings of good forms work well too, using the new growth.

When a plant is as dense as this one is, some hedge clippers would probably do the pruning very well.

Although the flowering time is limited to about 2 months at the most, the creeper on the fence stays green and dense for the rest of the year.

There are white and pink forms of this plant. The pink is particularly pretty but does not seem to be as robust as the others.

Bonsai Australian Plants

On Gardening Australia on ABC TV tonight this story about Bonsai Australian Plants was shown. I have often admired these and thought I would love to try some. However, as potted plants and I don’t always get along, I dismiss it as being doomed to failure. Seeing some of the plants on TV was great and there is a photo to see on the site. I have copied the text here.

“Hi. I’m Brian Sampson. I’m probably better known in public life as an Essendon footballer. I was fortunate enough to play in a couple of premiership teams, in ’62 and ’65. I’ve been 50 years a bricklayer, many years a netball coach and now a passionate lawn bowls player but bonsai has been a big part of my life.

“When I first started, back in the 1980s, there were a few people who grew natives but now there are more people growing natives in their collections and a lot of great bonsai growers around Australia. If you’ve got a bit of artistic flair and a bit of imagination, the world’s at your feet.

“Once I used to go for a drive in the bush and there were just trees. Now I look at different tree styles in the bush and imagine how to incorporate them as a bonsai. Australian natives are particularly suited to what I like doing – landscapes – because a landscape has to look natural and you don’t have to design them by the rules of bonsai.

“The ideal height to see all the details of a bonsai tree is about 2 feet. Then you can see the beautiful details of the roots, the bark, all the little knots and gnarls on the tree, which gives an illusion of age. And the furrowed look on the bark of the paperbarks and callistemons – it’s a natural aged look. Really, bonsai is an illusion. You have to learn to make a tree look old. It’s not because it is old. You make it look old.

“Some favourites in the collection are: an Angophora, which is beautiful when the bark starts peeling off and the Quercus suber, or evergreen oak which is what they make cork out of.

“There are so many varieties of native trees in Australia. We have the beautiful paperbarks, the bottlebrush, wattle, and Australian eucalypts. We’ve only scratched the surface. There’s literally hundreds of potential bonsai that we haven’t even touched yet.

“To make a bonsai using an Australian native such as a Callistemon ‘Captain Cook is very easy to do. The first thing, to bring out the best features of an Australian native, is to expose the top 3 inches of roots and branch (that are usually below the soil) for a lovely gnarled look.

“The next stage is to tease the roots. Take off as much as is safe around the base of the plant. Now work out which branches need to be taken off because they are impeding the style of the tree. Cut off any little branches and peel the bark back to expose any dead wood.

“In the pot, it’s very important to have gauze over the drainage holes, so the soil doesn’t dry out. Two wires are used to hold the plant secure in the pot.

“Add a little bit of drainage gravel, then a little potting mix. It’s a mixture of pine bark, peat moss and some fine gravel.

“Try to plant the tree at the right angle. This part is important. Wire the tree in. There are two different types of wires used in bonsai – aluminium or copper. Copper is stronger. Aluminium is a little more pliable. I tend to use aluminium.

“With Australian natives, apply a little bit of wire but it’s better to apply the clip-and-grow method. Now that I’ve wired these few branches on the callistemon, I am very excited about this tree becoming a great Australian native bonsai.”

Chrysocephalum apiculatum

Chrysocephalum apiculatum (grey leafed form)

I have just been potting on some struck cuttings of three different versions of Chrysocephalum apiculatum. All have golden yellow ‘billy button’ flowers, are perennial, some are suckering, and there are a number of leaf forms.

These plants need tidying up when new growth begins at the base of the plants.

My favourites have grey/green leaves and one has distinctly grey leaves. Of course the flowers look great against these leaves. The mallee form is a small clumping plant, with smaller flowers and green leaves. It is a dainty plant compared to the brashness of the others.

Hardenbergia violacea (Native Wisteria)

Hardenbergia violacea is a hardy climbing plant which comes in purple, pink or white sprays of pea shaped flowers. I have also seen a plant with bluish sprays of flowers. The clusters of flowers are what gives this species its common name. This is also successfully grown as a scrambling plant hanging down an embankment. It sometimes grows as a scrambling shrub rather than as a climber.

Top 5 Drought Tolerant Australian Native Plants…

…in five categories.

I decided that I would set 5 simple categories of plants and list five species within those categories.

Drought Tolerance is relative and what I have chosen are plants that are drought tolerant in an area with less than 14 inches (350mm) of annual rainfall (winter wet). Other issues which can make a difference are severe frosts, drying winds, the amount of rainfall the previous winter and whether mulch is used or the amount of shade available.

Ground Covering Plants

  1. Hardenbergia violacea (purple, pink, white) Native wisteria (Also a climbing plant)
  2. Chrysocephalum apiculatum (suckering plant with small yellow pom pom heads.
  3. Kennedia prostrata (Running Postman – because of red and black flowers and very flat form.
  4. Eremophila glabra (Emu Bush) (various prostrate forms, different colours)
  5. Myoporum parvifolium vigorous flat ground cover with white flowers

Small Shrubs to 1 metre

  1. Eremophila macdonnellii (large deep purple flowers)
  2. Eremophila macdonnellii (large deep purple flowers)
  3. Prostanthera magnifica (Mint Bush with very large flowers)
  4. Thryptomene saxicola (Pink or white small flowers)
  5. Grevillea lavandulacea

Tufted Plants

  1. Dianella revoluta (Purple nodding flowers and purple berries)
  2. Orthrosanthos multiflorus (Native Iris) (Mauve Blue flowers)
  3. Wahlenbergia communis (native Bluebell) (perrenial with blue star flowers.)

  2. Melia azedarach (White Cedar)
  3. Callistemon viminalis (Weeping Bottlebrush)
  4. Agonis flexuosa (Native Willow)
  5. Melaleuca lanceolata (White bottle brush flowers)

These are some of my favourite plants and ones that I know to be successful. These are all growing in garden conditions. Growing the same plants in the field is another matter altogether and another list would need to be generated.

I haven’t been able to get to my blog for several weeks and this opportunity to participate in the latest Problogger writing project provided me with the push to get going again.
