The inflorescence shows thick, up to 12 cm long, male catkins that hang down gracefully and inconspicuous reddish female flowers. They appear well before the leaves. The edible nuts are surrounded by capriciously grown glandular husks and are circa 2 cm across. C. colurna has a deep-rooting root system.
