Grassy woodland on moderately fertile loamy soils.
Tree to 25m high. Open crown of dull olive-green leaves. Grey, fibrous-flaky "box" bark with whitish patches, upper branches smooth-barked.
Often confused with White Box (E. albens). Grey Box has greener and narrower leaves than White Box, and smaller buds and fruit.

Long-lived. Moderate growth rate.
White, Feb-Jun. Flowers freely each year.
Throughout year, as seeds generally retained. Good crops may be irregular.
From seed (±729 seeds per gram).
From seed, particularly in absence of competitive exotic grasses or weeds, during wet summers. Coppices vigorously from low stumps, and regrowth is long-lived. Establishes well when direct seeded.
Shade and shelter
Useful medium-level cover in windbreaks. Good shade due to spreading crown.
Useful in gully erosion control behind fibrous-rooted understorey species.
Pale, very durable, tough and strong. Density about 1100 kg/m3. Used for posts, poles, fencing and heavy construction. Interesting furniture timber, although difficult to work.
Excellent habitat. Flowers are a food source for Sugar Gliders, Squirrel Gliders, native birds and insects. Insect-eating birds attracted. Hollows are nesting and refuge sites for native birds and mammals. Critical habitat for the Grey-crowned Babbler, Stone Curlew and goannas.
No outstanding features, although may be suitable for larger gardens and parks.
Leaves produce a range of dyes depending on mordants used.
