Documented by Léo — grown in the ground, USDA zone 8b
Bouquetier de Nice sour orange is a traditional French selection historically grown on the Côte d'Azur for the production of orange blossom water and neroli essential oil. Its hardiness reaches about 18°F (−8°C) on the tree, with a USDA zone 8a climate benchmark used in this entry, indicative and to be confirmed for this cultivar; a sheltered location and frost protection remain necessary. The vigorous tree reaches 10 to 16 ft (3 to 5 m) with a compact, rounded habit, evergreen foliage, and exceptionally abundant, highly fragrant white flowers in spring, the main use of the variety. Its bitter orange fruits, medium-sized, with thick, rough skin, ripen in winter. The variety is grown for its flowers (floral water, Grasse perfumery) more than for its fruit, which remains excellent in marmalade. Graft onto Poncirus trifoliata, south wall, well-drained soil.
