Plumeria Alba
The Plumeria Alba, also known as white frangipani, is a majestic tropical shrub renowned for its immaculate five-petaled flowers with a bright yellow center. Native to the Caribbean, it is now appreciated in tropical gardens and greenhouses worldwide for its refined appearance and intoxicating sweet fragrance. Its graphic growth habit, long dark green leaves, and knotted branches give it a highly decorative, sculptural silhouette.
An emblematic plant of Asian temples and tropical islands, the Plumeria Alba immediately evokes exoticism and a relaxed lifestyle. Grown in pots or planted in the ground in warm regions, it quickly becomes the focal point of a garden, balcony, or veranda.
The Plumeria Alba originates from the Caribbean, where it grows in sunny, well-drained soils. It belongs to the Apocynaceae family. Unlike other species of the Plumeria genus, this one is distinguished by its pure white flowers with a waxy texture and an especially powerful evening fragrance.
In its natural habitat, it is found on dry, often limestone-rich soils and can reach heights of 5 to 7 meters. Its ability to withstand periods of drought makes it an excellent candidate for hot and dry climates.
