Eucalyptus suberea is a mallee or small tree that typically grows to a height of 3–6 m (9.8–19.7 ft) and forms a lignotuber.

The flower buds are arranged in leaf axils on an unbranched peduncle 6–15 mm (0.24–0.59 in) long, the individual buds on pedicels 2–4 mm (0.079–0.157 in) long.

[6][7] The specific epithet (suberea) is from the Latin word subereus and refers to the rough, corky bark of older specimens.
