Jasminum grandiflorum, commonly known as Royal Jasmine, is a species of jasmine native to South Asia and widely cultivated in warm temperate and tropical regions around the world. The plant is a deciduous shrub that can also behave as a climber, reaching up to 2-4 meters in height. It is characterized by its dark green, pinnate leaves and prolific flowering. The flowers of Jasminum grandiflorum are particularly notable for their size and fragrance, making them highly valued both in the ornamental garden and in the perfume industry.
The blossoms are large, usually white or pale pink, and appear in clusters. They bloom primarily in the summer and into the fall, although in very warm climates, the plant may flower almost continuously throughout the year. Each flower opens at night and may remain open until sunrise, exuding a complex, sweet-scented aroma that is richer and slightly more intense at night.
The scent profile of Jasminum grandiflorum is deeply floral and intensely fragrant, with sweet, heady notes that are often described as intoxicating. The aroma is multi-layered, combining the opulence of white flowers with subtle hints of green and fruity undercurrents, creating a sumptuously rich bouquet that is both refreshing and soothing. This fragrance is particularly prized in perfumery, where it is used to add depth and warmth to floral perfumes, often serving as a middle or base note.
