Leptospermum scoparium, commonly known as manuka or tea tree, is a flowering plant native to New Zealand and southeastern Australia. While it is best known for its medicinal properties and as a source of honey, manuka also has numerous synonyms that reflect its diverse uses and regional variations. In Australia, it is often called jellybush, while in New Zealand it may be referred to as kanuka or kahikatoa. Other synonyms include red-tea tree, white tea tree, and manuka-myrtle. Regardless of the name used, manuka remains a valuable resource for both traditional and modern medicine, as well as a cherished part of New Zealand's cultural heritage.
