Persoonia acerosa is an evergreen shrub that can grow up to 1.80 metres tall.
It is harvested from the wild for local use as a food.
Australia - New South Wales.
Heaths and dry sclerophyll forests in sandy stony soils[
]. Found at elevations of 550 - 1000 metres[
We have very little information on this species and do not know how hardy it will be in Britain. Plants tolerate temperatures down to at least -7°c in Australian gardens, though this cannot be translated directly to British gardens due to our cooler summers and longer colder and wetter winters. This species hybridises sporadically in the wild with P. levis and P. myrtilloides[
]. The following notes are based on the general needs of the genus.
Requires a warm position in full sun in a freely draining preferably sandy slightly acid soil, preferring a pH around 6.3 to 6.5[
]. Soils should be low in nutrients, especially nitrates and phosphates[
Fruit - raw or cooked. Succulent but astringent[
]. The fruit has a sweet fibrous pulp that is fixed to one large seed, it tastes somewhat like sweet cotton wool and is relished by the Australian Aborigines[
Seed - scarify the seed and sow it in a greenhouse as soon as it is ripe in the autumn. Keep the seed tray in a sunny position during the following summer and the seed should germinate in the autumn. About 46% germination can be expected. Carefully prick the young seedlings out into individual pots within 1 - 2 days of emerging, the root is very brittle and plants are easily killed[
]. Grow the plants on in the greenhouse for at least their first 2 winters and plant them out into their permanent positions in early summer. Give some protection from winter cold for at least their first winter outdoors.
