Tough ironbark with deeply furrowed black bark and pink, red or cream blossom from autumn to spring.

Its hard, black, deeply furrowed bark makes it one of the most distinctive gums. Flowers come through the cooler months, when they are an important nectar source for honeyeaters, lorikeets and bees. Pink-flowered forms are popular as street and park trees.
