Learn about identifying, growing and using Australian Indigenous Plants for Food
There are many Australian plants that are edible, and even some that are in very high demand as foods throughout the world.  The Aborigines lived off the land before white civilization came to Australia. Plants contributed significantly to their diet.

There are many different types of bush tucker foods:

  • Nuts and seeds (eg. Acacia, Macadamia, bunya nuts)
  • Drinks (eg. hot teas, infusions of nectar laden flowers, fruit juices)
  • Flavourings (eg. lemon scented myrtle)
  • Berries (eg. Astroloma, some Solanum species)
  • Fruits (eg. quandong, Ficus macrophylla, Syzygium)
  • Vegetables
  • Wattle seeds ground to produce ‘flour’
  • Plant roots ground to produce a paste or flour.

Designing an edible garden is not that different to designing any type of garden; you need to give thought to what will grow in your area and climatic zone, which plants you will incorporate into the garden and how to arrange these plants for aesthetic value. Unlike a ‘normal’ garden however your design will most probably not be cut into sections i.e. vegetable garden, fruit garden and ornamental garden. The edible ornamental bush garden you design can include all those features within it, without separation.  

A natural edible garden need not be boring or look untended. If carefully designed it can incorporate all the normal design elements that make bush gardens interesting and beautiful, the only difference is that you will be consciously choosing plants that can be harvested for their edible produce.
 
What Trees are Bush Tucker Plants?
Here are a few to try.

Acacia longifolia (Golden Wattle)
A fast growing tree 7-10m tall native to south eastern Australia, lower southeast of  Qld, Eastern NSW, eastern and southern Victoria and south eastern SA. Green wattle seeds are quite similar in composition to cultivated garden peas but are best cooked by lightly baking. Flowers appear in July through to September with seed pods ripening in summer.

Acacia mearnsii
This plant is found in southern Victoria, South Australia, Tasmania as well as the coast and tablelands of New South Wales. Flowering occurs from September to December. Edible gum and seed; bark tea is used for indigestion.  This tree grows to 15m and needs an open, dry, well-drained positioning full sun.

Backhousia citriodora (Lemon Myrtle)
A small, low branching tree, 3m - 8m tall native to Qld and NSW It needs warm, well-drained soil and grows in full sun to part shade; protect from frost. The leaves are intensely lemon flavoured used in teas, as a lemongrass substitute. Wonderful in cheesecakes; dry and grind the leaves for cakes and biscuits.

Brachychiton populneus (Kurrajong)
Large tree to 10m requires a moist, well-drained position; frost tender when young plant in sun to part shade. Nutty flavoured edible seed.

Citrus australasica (Native Finger Lime)
A small tree, 4m - 6m tall native to Qld and NSW that grows in full sun to part shade on moist, fertile, well-drained soil but can also be grown in pots. The finger shaped fruit is filled with edible tiny balls they have a lovely lime taste great in Asian dishes but also suited to cocktails.

Eucalyptus olida (Strawberry Gum)
A medium-sized tree to 20m, restricted to sclerophyll woodlands on the Northern Tableland of NSW; cream flowers are followed by small woody capsules. The juvenile leaves are ovate, dull green and 7cm long. The intensely aromatic adult leaves are to 17cm lanceolate, glossy green and are used as a spice. E.olida is classified as threatened species in the wild, but is becoming more common in cultivation due to its essential oil and spice qualities; suited to larger gardens.

Macadamia integrifolia (Macadamia Nut)
A rounded, slow growing tree 12 - 15m tall; for best results buy a grafted variety (these are readily available in Australia). Best suited to the warmer climates of coastal south Qld and northern NSW. The delicious nuts should be allowed to ripen on the tree. Nuts ripen approx. 7 months after flowers appear in June through to March. Bronze leaves appear opposite in seedings and in whorls of 3 and pale green on mature plants, 10–30 cm long, margins with few or no spines, petioles (leaf stalks are about 1.3 cm long.  Flowers creamy-white, without petals are borne in groups of 3 or 4 along a long axis in racemes, similar to grapes. The fruit consist of a fleshy green husk enclosing a spherical shaped seed the nuts are roundish and 1.3–2.5 cm in diameter. The shell is tough, fibrous and quite difficult to crack; (more on this species in the following lesson).

Syzygium luehmannii (Riberry)
A small bushy tree to 8m needs well drained fertile soil and full sun to semi shade; native to Qld and NSW. A lovely compact, medium tree sized with foliage to ground level. Small white flowers are followed by fleshy red berries. The small, glossy, lance-shaped leaves are pink/red when young. They are opposite, simple, entire, lanceolate to ovate in shape on a 2-3mm leaf stalk; leaves are 4 to 5 cm long with a long prominent point.  Small 2.5cm panicles of white or cream petal flowers (petals appear in 4 s or 5s) form at the ends of branchlets in November or December. Flower stamens are 2 to 5 mm long. Pear shaped 13mm long red berry fruit containing a single seed, matures in December to February. Cuttings of this plant strike easily although seeds can be used but germination is sporadic and unreliable. The sweet purple berries have a tart after-taste and are great in jams, sauces to accompany meat or as cordial. Prune after flowering to maintain compact growth.
