Syzygium aromaticum, commonly known as Clove, is an evergreen tree native to the Molucca Islands’ tropical rainforests, also historically known as the Spice Islands, located in Indonesia. It can grow to a height of 8–12 meters (26–39 feet) and is characterized by its large, aromatic leaves and clusters of crimson flowers at the branch tips. The flower buds, which are the source of the spice, start with a pale hue before turning green and finally bright red when they are ready to be harvested. Cloves are picked when they are 1.5–2 centimeters (0.59–0.79 inches) long. The harvested bud consists of a long calyx that ends in four spreading sepals and a central ball of four unopened petals.

Clove trees are valued for their aromatic flower buds, which are used as a spice in cuisines worldwide and have medicinal properties. They are cultivated in tropical climates, often in spice gardens or plantations. Clove trees require full sun exposure and consistent moisture, thriving in well-drained, fertile soils. They are not tolerant of cold temperatures and need protection from strong winds. Clove oil, derived from the buds, leaves, and stems, is used in traditional medicine and as a flavoring agent. The tree’s dense canopy and evergreen nature make it suitable for ornamental use in suitable climates. However, it can be susceptible to pests like stem borers and fungal diseases such as leaf spot.CC BY-SA 4.0
