Elaeocarpus dentatus aka Elaeocarpus Dentatus

Elaeocarpus dentatus is an evergreen tree native to New Zealand. It belongs to the Elaeocarpaceae family. Its range includes both North Island and South Island. It grows in lowland forests, reaching south to about 44°18′ south. The tree keeps its leaves throughout the year. The reported height reaches about 59 feet [18 metres].

Its flowers have both male and female organs. The fruit measures about 0.6 inches [15 millimetres] across. It has food uses after preparation and cooking. One method involves soaking the fruit, then rubbing and sieving it. This removes the stalks and skins before baking it into cakes. The resulting food has an oily taste. The fruit can also be pickled and eaten like olives. The source lists no known hazards, but gives no detailed safety assessment.

This tree prefers fertile soil rich in humus. It needs moisture, but the soil should drain well. Sandy, loamy and clay soils can all suit it. It accepts very acid to neutral soil conditions. One cultivation account calls for soil free of lime. It can grow in full sun or light woodland shade. A woodland garden, sunny edge or dappled shade offers a suitable setting. These options allow it to fit several parts of a sheltered garden.

In Britain, outdoor growth is limited to the mildest gardens. Shelter helps, including a position beside a south-facing or southwest-facing wall. It can also grow in woodland gardens in mild areas. Plants For A Future lists USDA hardiness zones 8–11. Its bark supplies tannin and a blue-black dye. The same source records no known medicinal uses. The supplied accounts do not describe specific pests or diseases.

Seeds can be sown in a greenhouse in spring. Germination may take two years or longer, so seedlings need patience. Move seedlings into separate pots once large enough to handle. Keep them in the greenhouse through at least their first winter. Plant them outside in late spring or early summer, after expected frosts. Cuttings offer another way to raise new plants. Take almost-ripe shoots in August or September, keeping their leaves attached. Root them in sandy soil within a frame.
