There are over 700 species of flowering trees, shrubs or mallees (multi-stemmed trees) in the genus, most native to Australia today. Fossil evidence shows that they were Gondwanan. Wildfire is a natural part of Eucalypt forests and the plants regenerate from underground lignotubers.
Many have interesting bark and they actually grow a new layer of bark every year. Sometimes old layers peel, revealing interesting colors underneath. Most of the species are evergreen and the leaves exude oil. They dislike cold and are killed by hard frost.
