Juglans regia is a long-lived tree that grows well in areas of Australia with a Mediterranean climate. The produce of the tree is a large nut with a small kernel and good flavour. Green husks split open dropping nuts on the ground during autumn. Walnut trees are grown in many home gardens as an ornamental tree as it has an attractive spreading canopy and lush foliage. In good soil and the right climate, the trees produce an abundant crop. In poorer soils, the trees will be smaller and nut production will be limited.

Soil: Well-drained loam soil.
Conditions: Full sun to semi-shade. Frost tolerant.
Size: Height 10-25m x width 2-4m
