Edible Uses

Edible Parts: Fruit;  Seed.
Edible Uses:

Fruit - raw or cooked[2, 92, 105, 161]. Sweet, dry and mealy[61]. An important food for native tribes, it can also be dried for winter use[177]. When dried and baked into a bread it is relished by the native Indian tribes[2]. If harvested when not quite ripe, it can be used like a tart apple[2]. A cooling sub-acid drink can be made from the fruit[2, 257]. The fruit is about 8 - 10mm in diameter[200]. Seed - ground into a powder and used to make mush, biscuits etc[92, 257]. The seed is very small and would be difficult to separate from the fruit. It would be easier to dry the whole fruit, grind this into a powder and use it in soups etc[K].

Medicinal Uses



Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.

Antiseptic;  Appetizer;  Astringent;  Diuretic;  Stomachic.

The dried leaves are used in the treatment of a variety of complaints[4]. These leaves should be harvested in early autumn, only green leaves being selected, and then dried in gentle heat[4]. A tea made from the dried leaves is strongly astringent, diuretic and an antiseptic for the urinary tract[4, 222]. It is much used for kidney and bladder complaints and inflammation of the urinary tract, but it should be used with caution[4, 21, 46, 172] because it contains arbutin which hydrolyzes into the toxic urinary antiseptic hydroquinone[222]. An infusion of the bark powder has been used in the treatment of lung haemorrhages[257]. A cider made from the fruit has been used as an appetizer to create appetite and treat stomach complaints[257]. Although the report does not specify, the cider was probably unfermented[K].

Other Uses

Dye;  Wood.

A yellowish-brown dye is obtained from the leaves, it does not require a mordant[168]. The wood is used for making fine furniture[61].

Cultivation details

Requires a deep moist well-drained light or medium lime-free loam[11, 166, 200] in sun or semi-shade but plants produce less fruit when they are grown in the shade[200]. Tolerates maritime exposure. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c[200]. Very closely related to A. columbiana but with a more southerly range[11]. Plants can regenerate after a forest fire from a mallee-like base[166]. Plants resent root disturbance and should be placed in their final positions as soon as possible[11, 134].

Propagation

Seed - best sown in a greenhouse as soon as it is ripe. Pre-soak dried seed in boiling water for 10 - 20 seconds or burn some straw on top of them and then stratify at 2 - 5°c for 2 months[11, 200]. The seed usually germinates in 2 - 3 months at 15°c[134]. When large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame or greenhouse for at least their first winter. Plant out in late spring or early summer. Cuttings of side shoots of the current season's growth, 5 - 8cm with a heel, August to December in a frame. The cuttings are very slow and can take a year to root[1, 78]. Division in early spring. Take care because the plant resents root disturbance. Pot the divisions up and keep them in a lightly shaded position in a cold frame or greenhouse until they are growing away actively. Layering in spring[200].
