Plumeria rubra is a deciduous shrub or small tree, native to Mesoamerica, commonly grown in tropical and subtropical regions worldwide. It typically reaches heights of 6–8 meters. The branches are thick and fleshy, containing a characteristic milky latex. The inflorescences are terminal, bearing bisexual, actinomorphic flowers. The corolla is salverform (tube-shaped with spreading lobes), with five petals fused at the base. In this variety, the petals are pink with a yellow to orange center, arranged in a spiral pattern. The flowers are waxy in texture and strongly fragrant. The androecium consists of five stamens inserted inside the corolla tube. The gynoecium is superior, bicarpellary, with a single style and bifid stigma. Plumeria rubra flowers primarily in warm and dry seasons. It is an allogamous species (cross-pollinated), often pollinated by insects or butterflies. It prefers well-drained soils and full sun exposure. It is commonly propagated through woody stem cuttings and is highly valued in ornamental horticulture for its prolonged blooming period, fragrant flowers, and ease of cultivation.
