Angophora floribunda

Angophora floribunda is an evergreen tree in the myrtle family. Its common names include rough-barked apple and broad-leaved apple. It comes from eastern Australia, including Queensland, New South Wales and Victoria. It grows mainly in subtropical regions, with some reach into the tropics. It occurs near the coast, often on river flats. It also grows on shale soils and in other habitats. In New South Wales, it reaches about 3,940 feet [1,200 metres] above sea level.

Sources give a height of about 59 feet [18 metres]. A broader range runs from 33–66 feet [10–20 metres]. The tree forms a large crown of light-green leaves. Its branches twist, giving some trees a bent, uneven shape. Trees grown in open ground often have short trunks. These can measure about 1.6–3.3 feet [0.5–1 metre] across. The leaves stay on the tree throughout the year. Sources report that it sheds bark each year.

The flowers have both male and female parts. Bees visit them and carry pollen between flowers. This gives the tree value as a food source for bees. People also gather its wood and resin from wild trees. Gum taken from the trunk has served to preserve ropes used in water. The supplied sources list no known food or medicinal uses. They report no known hazards, but do not establish safety for people or pets.

Grow this tree in full sun rather than shade. It prefers soil that drains well but holds some moisture. Sandy and loamy soils suit it. Moderate soil fertility is enough, and it also tolerates poor ground. Sources differ on its preferred soil pH. Both support mildly acid to neutral conditions. One also allows mildly alkaline soil. Established trees cope with drought, though moist soil suits their growth. Strong winds can break branches, so wind exposure limits its use.

Cold tolerance varies between the source accounts. One reports survival at 19°F [-7°C] in Australian gardens. Another warns that 23°F [-5°C] can kill mature trees. New shoots may suffer damage at 30°F [-1°C]. These figures do not transfer neatly to Britain's cooler, wetter winters. Outdoor growing there is limited to the mildest areas. Seedlings need a warm, sunny start under glass. The cited guidance keeps them sheltered through their first winter. It also calls for cold protection after planting outdoors.
