Notes

Fruit - raw or cooked[1][2][3][4]. Sweet, dry and mealy[5]. An important food for native tribes, it can also be dried for winter use[6]. When dried and baked into a bread it is relished by the native Indian tribes[1]. If harvested when not quite ripe, it can be used like a tart apple[1]. A cooling sub-acid drink can be made from the fruit[1][7]. The fruit is about 8 - 10mm in diameter[8]. Seed - ground into a powder and used to make mush, biscuits etc[2][7]. 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(Warning!)

The dried leaves are used in the treatment of a variety of complaints[10]. These leaves should be harvested in early autumn, only green leaves being selected, and then dried in gentle heat[10]. A tea made from the dried leaves is strongly astringent, diuretic and an antiseptic for the urinary tract[10][11]. It is much used for kidney and bladder complaints and inflammation of the urinary tract, but it should be used with caution[10][12][13][14] because it contains arbutin which hydrolyzes into the toxic urinary antiseptic hydroquinone[11].

An infusion of the bark powder has been used in the treatment of lung haemorrhages[7].

A cider made from the fruit has been used as an appetizer to create appetite and treat stomach complaints[7]. Although the report does not specify, the cider was probably unfermented[K].

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[15][8]. The seed usually germinates in 2 - 3 months at 15°c[16]. 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[17][18]. 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[8].

Cultivation

Requires a deep moist well-drained light or medium lime-free loam[15][19][8] in sun or semi-shade but plants produce less fruit when they are grown in the shade[8]. 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[8]. Very closely related to A. columbiana but with a more southerly range[15]. Plants can regenerate after a forest fire from a mallee-like base[19].

Plants resent root disturbance and should be placed in their final positions as soon as possible[15][16].
