Phyllocladus aspleniifolius aka Celery Top Pine

Phyllocladus aspleniifolius is an evergreen tree native to Tasmania. It belongs to the Podocarpaceae family. Common names include celery top pine and Tasman celery pine. Adventure Bay pine is another name for this species. It comes from a temperate climate with humid forest habitats. These include rainforest and more open Eucalyptus forest. In both settings, it grows in rich, damp sites.

In cultivation, it reaches about 33 feet (10 metres) tall. Its spread reaches about 16 feet (5 metres). Growth is slow, and British-grown plants can grow very slowly. Kew records its form as either a shrub or tree. It keeps its foliage throughout the year. Male and female reproductive structures occur on the same plant. Wind carries the pollen between them. The supplied species evidence gives no flowering season or fruit details.

This tree needs a moist site and a humid climate. It does best with ample rain and warmth. A good loam with leaf mould suits it well. It can also grow in sandy or clay soils. Its soil range includes mild acidity, neutral conditions and mild alkalinity. It tolerates both full sun and light woodland shade. A woodland garden or sunny woodland edge offers possible planting sites. Its need for warmth and humidity limits its use in Britain.

Plants For A Future lists USDA hardiness zones 8–11. Australian garden records report survival down to about 19°F (−7°C). That limit does not transfer directly to British gardens. Britain has cooler summers and longer, cold, wet winters. Outdoor planting may succeed in the mildest British areas. Sow seed in a cold frame in late winter. Grow young seedlings in separate pots once large enough. Keep them under glass through at least their first winter. Plant out after the last expected frost, in late spring or early summer.

The wood has uses in floors, boats and cabinet work. It is fairly heavy, works well and resists decay in soil. Moisture changes cause little swelling or shrinkage. The wood also resists some acids. Plants For A Future reports no known food or medicinal uses. It also lists no known hazards, but this does not establish safety. The supplied evidence identifies no specific pests or diseases.
