It has rough, fibrous or flaky bark, dull greenish-grey, lance-shaped leaves, oval to club-shaped green to yellow flower buds, white flowers and hemispherical, cup-shaped or barrel-shaped fruit.

Eucalyptus largiflorens is a tree that grows to a height of 20 metres (66 ft) with rough bark to the thinnest branches.

The flowers are arranged in groups of mostly between seven and eleven on the ends of the branches or in leaf axils on a cylindrical peduncle 3–11 mm (0.12–0.43 in) long, individual flowers on a cylindrical pedicel 1–5 mm (0.039–0.20 in) long.

[3][5][6][7][8] Eucalyptus largiflorens was first formally described in 1855 by Ferdinand von Mueller and the description was published in Transactions and Prodeedings of the Victorian Institute for the Advancement of Science.

Once the seeds were extracted, they were soaked and treated with several changes of water to remove the bitterness.
