Night-flowering jasmine

Night-flowering jasmine (lat. Nyctanthes arbor-tristis) is a prominent member of the Oleaceae family. Often referred to as the tree of sorrow, this plant is famous for its fragrant white flowers with orange-red centers that bloom at night and fall off during the morning, creating a natural carpet under the tree canopy.

Native to Southeast Asia, specifically India and surrounding regions, this species thrives in tropical and subtropical environments. It has been cultivated for centuries not only for its ornamental value but also for its industrial and medicinal potential. The tree is well-adapted to varied soil types, provided there is adequate drainage and exposure to sunlight.

Botanically, the plant features ovate, rough-textured leaves and slender, woody branches. The inflorescences are distinct, appearing in small clusters. When cultivated as a crop, it requires systematic pruning to manage height and maximize flower yield, which is the primary economic component harvested from the tree.

Agronomic requirements include a warm climate with distinct humidity levels. While it is hardy in many respects, it performs best in loamy soils enriched with organic matter. Growers typically use seed propagation or semi-hardwood cuttings for reproduction. Irrigation management is critical during the initial growth phase, but mature trees show good tolerance to temporary dry spells.

Economically, the plant is valued for the orange pigment extracted from its corolla tubes, used to dye silk and cotton. In pharmaceuticals, it is investigated for its anti-arthritic and antiviral properties. Furthermore, the essential oils derived from the flowers are high-value ingredients in the perfume and cosmetic industries.
