When just a scented candle won't do

New York

A FRAGRANCE called green tea blows through the corridors of Sonesta hotels worldwide courtesy of Air Esscentials, a 10-year-old company in Miami that sells scent-diffusing systems. Green tea lemongrass, another Air Esscentials creation, is the aroma of choice at Morgans Hotels worldwide.

Now, those very same smells are also perfuming the living rooms and bedrooms of many private residences.
