Melaleuca leptospermoides is a shrub growing to a height of 1.6 m (5 ft). The leaves are arranged alternately, are 4.5–12 mm (0.2–0.5 in) long, 1.3–6 mm (0.05–0.2 in) wide and linear to narrow oval in shape.
Purple, mauve, magenta or pink flowers appear in heads at or near the ends of the branches. The heads are composed of one to four groups of flowers with three flowers in each group and are up to 22 mm (0.9 in) in diameter. The stamens are arranged in five bundles around the flower, each bundle having 8 to 12 stamens. Flowering occurs between September and November and the fruit which follow are woody capsules, 4–5 mm (0.16–0.20 in) long.
