General Description

Arabian jasmine has been cultivated since ancient times for its intensely fragrant, white flowers. Widespread in distribution, this shrubby, evergreen climber is thought to have originated in southern Asia, and was probably brought by traders to the Middle East and other areas. Its blossoms are used in China to make jasmine tea, for fragrant leis in Hawaii and the Philippines, and in the manufacture of perfume. It is the national flower of both Indonesia and the Philippines.

The cultivar ‘Grand Duke of Tuscany’ bears many loose clusters of double-form (extra petal) blossoms that resemble white roses or gardenias. They bloom generously throughout the summer, and may continue sporadically throughout the year. The long, vining stems are clad in glossy, dark green, pointed oval leaves which are grouped in opposite pairs or whorls of three. This cultivar looks rather ratty when not in bloom, and therefore is prettiest when clambering over a wall or among other shrubs in a mixed border.

Hardy in tropical, frost-free climates, 'Grand Duke of Tuscany' needs full to partial sun and moist, fertile, well-drained soil. It is also somewhat tolerant of dry conditions. The plant may be gently pruned to form a shrub, or trained to climb a wall, fence or other supportive structure. It is also suitable for use in containers. Be sure to grow it near a patio, window or swimming pool where its intoxicating fragrance can be fully enjoyed.

Because of its ability to self-seed, cultivars of Arabian jasmine are sometimes considered invasive in subtropical and tropical regions, including Florida.
