Bouvardia longiflora, commonly called the scented bouvardia, is a flowering plant species in the Rubiaceae family. It was first described by Spanish botanist Antonio José Cavanilles in 1801, based on a specimen from the collection of Luis Née. Its holotype specimen was collected from a location between Querétaro and Guanajuato. This species is the most widely cultivated member of the Bouvardia genus, grown specifically for its fragrance. In garden cultivation, it grows best in sheltered positions with good soil drainage. Its scent is strongest during the evening, and it can tolerate a minimum winter temperature of 50 °F.
