Most of the approximately 700 species in this genus of evergreen trees are native to Australia. They belong to the myrtle family, noted for its aromatic leaves. Eucalypts range in size from immense, single-trunk, forest trees to the small multi-stemmed shrubs called mallees. Various distinctive bark types have given rise to many common names such as gums, boxes, stringybarks, and ironbarks. The eucalypt flower bud has an enlarged floral receptacle and a cap, which covers numerous stammens and is shed when the flower opens. The many fluffy stamens may be white, cream, yellow, pink, or red. Eucalypts are adaptable to a wide range of climatic conditions and are cultivated in many parts of the worls.
CULTIVATION
Most species are fast grown and long lived, and once established require little artificial watering or fertilizer. They are best suited to warm-temperate or semi-arid regions. Frost hardiness varies, as do requirements for moist or dry conditions. Propagate from seed, which germinates readily.
Top Tip
Pruning is not essential, though many Eucalyptus species can be cut back and shaped if desired.
