Answer: You might be referring to Bouvardia longiflora (also called B. humboldtii). According to the Sunset Western Garden Book, this flower is used in bouquets, and has an aroma similar to jasmine.
The plant is native to Arizona, New Mexico, Mexico, and Central America. It is an evergreen shrub (2-3' tall) with showy clusters of tubular flowers. The variety 'Albatross' is white; the variety 'Stephanie' is more compact and tends to have more flowers.
