Plumeria became a popular ornamental plant in Europe during the 19th century, driven by increased colonial exploration, global trade, and the fascination with exotic flora. European botanists and horticulturists encountered Plumeria during their travels and expeditions to tropical regions, and they were captivated by the plant’s beauty and fragrance. The exotic appeal of Plumeria sparked a craze for growing and collecting these tropical gems among European aristocrats and the upper class. Plumeria cultivation spread to botanical gardens and greenhouses, where the plant’s propagation and hybridization were studied and refined, contributing to the diverse range of Plumeria cultivars available today. The European fascination with Plumeria fueled its popularity and dissemination throughout the continent.
