Edible Uses

Edible Parts: Fruit
Edible Uses:

Fruit - raw. A sweet and pleasant flavour[2, 105, 177]. The fruit is about 5mm in diameter[200]. [**CAUTION! The berries are not edible according to Crowe, the main authority on New Zealand edibles,see page 165 A field Guide to the Native edible plants of New Zealand 1997 edition. He says the error probably started with Sturtevant getting confused with Tawa (Beilschmiedia tawa, one of the best N.Z edibles I think, if you can adjust to fruit tasting like potato)which has a similar Maori name. He does not however say it is poisonous and it is not listed anywhere as poisonous as far as I can see. It was however very valuable to Maori for other uses above and bark was once exported for very high tannin content. David Nicholls, New Zealand]

Cultivation details

Prefers a light rich soil[1]. Succeeds in a fertile well-drained circum-neutral loamy soil, with shelter from cold winds[200]. Plants are not very frost-tolerant, though they are probably hardy in the mildest areas of the country[11, 166]. The foliage of this tree when an adult is markedly different from the juvenile foliage, though plants begin to flower whilst still in the juvenile form[200].

Overwinter the young plants in a greenhouse for at least the first winter and plant out in their permanent positions in late spring or early summer. Give some protection for its first winter outdoors. Cuttings of half-ripe wood, 5 - 8cm with a heel, July/August in a frame[78].
