Masks blossom among roses at French perfume capital

May roses are blooming in Grasse, the birthplace of French perfumes, but out in the fields, some of those who pick them face a problem this year. "Working with a mask and not smelling," the flowers, "is pretty frustrating," horticulturist Carole Biancalana acknowledges. Biancalana can still tick off a list of adjectives to describe the "complex, multiple and varied" scent of the centifolia rose, a fragile variety that cannot even stand by itself in a vase.
