Ylang-ylang is a tropical tree native to Southeast Asia and is scientifically known as Cananga odorata. It is renowned for its highly fragrant flowers, which are yellow-green and star-shaped. The essential oil extracted from these flowers is widely used in perfumery and aromatherapy due to its sweet, floral, and slightly fruity scent. Ylang-ylang oil is believed to have various therapeutic properties, including stress relief, mood enhancement, and aphrodisiac effects. The tree itself can grow up to 12 meters tall and thrives in warm, humid climates. Its flowers are often harvested in the early morning when their fragrance is most potent.
