Information


The following is an Extract from the book "Growing Australian Natives" by John Mason, published by Kangaroo Press, 1997.

ACACIA Mimosaceae

AT A GLANCE
Number of species: More than 800 named plus many unnamed species native to Australia. It is the largest genus in Australia.
Natural habitat: Throughout Australia in a wide variety of climatic and soil conditions (though only a few from tropical rainforests).
Flowering: There will be a species flowering somewhere in Australia at any time of the year with the heaviest concentration of flowering times occurring between late autumn to late spring depending on the species and where it is planted. Some Acacias are amongst the most spectacular flowering native plants. Flower colours are almost universally shades of yellow, ranging from pale through to golden.
Hardiness: Most are very hardy.
Habit: Ground covers, shrubs and trees.
Foliage: Varies greatly in shape & size. Colours are generally green to bluish-grey or silver. Acacias may have either:
1) Bipinnate true leaves
2) Phyllodes which are modified leaf-like structures that carry out the functions of the true leaves which are absent at maturity in most species
3) Cladodes which are stems that carry out the functions of the leaves. Both true leaves and phyllodes are absent. Growth: Usually rapid.
Lifespan: Generally short-lived though some of the larger woody types (eg. A. decurrens and A. elata) can live a lot longer.

GENERAL CULTURAL NEEDS:
#Suited to most soils. Some are sensitive to high phosphorus levels.
A. spectabilis sensitive to boron deficiency.
Many are sensitive to over-wet soils.
#Borers are a major pest. Crusader bugs can also be a serious problem.
#Caterpillars are a problem on some feather-leaved types.
#Pruning is risky, often resulting in die-back although many species will respond well to light pruning immediately after flowering.
#Respond well to watering in dry periods.
#Propagation is by pre-treated seed ie. prior to sowing, place seed in a cup & pour boiling water over to soften the seed coat. Allow the water to cool before removing the seeds for immediate sowing.
The germination rate of seed after treatment is generally good. Seed can be sown in propagating mix, or direct seeded into soil or open ground. Seed stored in dry conditions will last for many years, but may equire protection from insect and fungus attack.
(See the section on seed propagation earlier in this text for more information on seed raising and germination techniques.)
Some Acacias have also been successfully propagated by cuttings, however this method is generally difficult. Usually those species with smaller leaves and phyllodes strike better than species with the large bipinnate leaves.



Books

Growing Australian Native Plants
By John Mason
Perhaps the best value for money Australian native plant book around. Covering 1400 cultivars, 260 genera and 94 colour photos: not to mention chapters on propagation, landscaping, pests, culture & more.



Videos

Australian Native Plants.
Covering both identification and culture, it presents more than 35 different naive plants. Various cultural techniques are explained including planting, staking, pruning, mulching and watering. A wide variety of native genera are shown including several species of Grevillea, Acacia and Eucalyptus. Details of each species are then presented, such as, propagation, pruning, pest control, uses & appearance.
