Description and Ethnobotany

Others - Plant Morphology	Growth Form: Small, evergreen tree with a dense, spreading crown. Habitat: Occurs in the tropics and subtropics, but it grows best in the tropics at altitudes of 0 - 1200 m. Trunk: Short, low-branching trunk has brown, smooth bark. Foliage: Glossy, opposite leaves are oblong to lanceolate with entire leaf margin and long tapering tip (9 - 26 cm long, 1.5 - 6 cm wide). Flowers: Large pom-pom shaped flowers (5-10 cm wide) are arranged in inflorescences known as corymbs. Fruits: Fleshy, pitted fruits are known as drupes (2.5 - 5 cm wide). They are whitish to yellow, round to egg-shaped and smell like rosewater. The fruit apex has a crown-like structure formed by a persistent calyx (the outermost layer of a flower that often resembles small leaves). Landscaping: This species is grown as a roadside tree or fruit tree in home gardens. Cultivation: This species is tolerant of most soil types including waterlogged soils. Optimal growth will occur in acidic to neutral soils (pH 5.5 - 7). Trees should be spaced 5 m x 6 m apart. It is susceptible to fungal diseases, such as root rot, leaf spots and anthracnose. Propagation: Propagate by seed, budding, air layering, and grafting. Propagation by seed is the most common method, but seeds do not store well and must be sown promptly.Etymology: The genus name "Syzygium" is derived from the Greek word "suzugos" which means joined. Syzygium used to be the name of a Jamaican plant species with paired leaves and branches. It is commonly known as Rose Apple, because the fruits can be distilled to produce rosewater.
Ethnobotanical Uses	Edible Plant Parts : Edible Fruits Food (Fruit or Vegetable) Others: Food: The fruits are consumed raw or cooked. Although this species is grown in home gardens for its fruits, it is usually not grown in commercial orchards. Other: Essential oils in the leaves are extracted by distillation and used in the perfume industry.
