Eupomatia laurina


Eupomatia laurina, commonly named bolwarra or sometimes native guava or copper laurel, is a species of shrubs to small trees, of the Australian continent ancient plant family Eupomatiaceae. They often grow between tall, larger specimens may attain and a trunk diameter of. They grow naturally in eastern Australia and New Guinea. In Australia, they grow as far south as Nowa Nowa in the humid forests of the warm temperate east of the state of Victoria through eastern New South Wales and Queensland north to tropical Cape York Peninsula. They are one of the ancient lineages of flowering plants, usually growing as part of an understorey in rainforests or humid Eucalypt forests.
They have glossy leaves, oblong–elliptic shaped, from long. The branches bear the globose to urn-shaped fruits of a green external colour, measuring diameter and yellowing when ripe with pale coloured edible jelly flesh inside, interspersed by many non-edible seeds. Germination from fresh seed commences after around three weeks and completes after five weeks, with a high level of germination. Cuttings are not advised as a method of regeneration.
The sweet, aromatic fruit is used as a spice-fruit in cooking, being included in beverages, jams and desserts. It is best used in combination with other ingredients that complement its strong flavour, and hence should be considered one of the Australian spices.
In cultivation E. laurina is frost sensitive and prefers a protected, semi-shaded site. It can be propagated from seed or cuttings. Cutting propagated trees produce fruit after two years. Seedlings take four to six years to fruit.
The whole genus known to science includes only two other species, each one only known from occurrences in small localised areas of Australia and separated from each other by over. E. bennettii occurs only in the north-eastern New South Wales to south-eastern Queensland region and E. barbata in the Wet Tropics of Queensland.
