BALTIMORE — Lately, it seems you don’t have to be anywhere near a garden to stop and smell the roses.

Smell is the latest way that businesses are attempting to woo customers, whether it be the vanilla and cloves wafting through the air at Williams-Sonoma or the pungent smell of colognes at trendy clothing chains.

Technology to spread the scents has become more elaborate and includes a device that pumps fragrances through ventilation systems. And it’s all in an effort to create scent branding that helps to attract and keep customers.

It worked on Tracy Spence, a nurse anesthetist who was shopping recently at In Watermelon Sugar, a home goods store in Baltimore, for a birthday gift for her child’s nanny.

“It smells so good in here,” she exclaimed.

Spence immediately began looking for the source. “It smells a little woodsy and like a seaside cottage – fresh and clean. Oh, and there are floral notes. What is that?” Spence asked saleswoman Tea Erbe.

Erbe is used to customers commenting on the pleasant smell of the shop. Leslie Stevenson, owner of In Watermelon Sugar, has been burning Votivo brand candles for the past 10 years because of their long-lasting and alluring aroma. The candles, which cost $26, burn about 50 hours.

Stevenson switches scents depending on the season. During the holidays, she used the spruce-and-rosemary Joie de Noel scent. The rest of the winter months, she turns to scents such as Moroccan figs or teak. During the summer months, she burns honeysuckle, red currant, grapefruit and clover.

“I try not to go overboard,” Stevenson said about the intensity of the candles. “Most people do enjoy having a store that smells good. It helps get people in the mood. It sets the tone.”

ScentAir Technologies Inc., a company based in Charlotte, N.C., that specializes in devices that deliver scents in businesses, is experiencing what it calls a “golden age” in scent branding. Its client list includes Ashley Furniture, Jimmy Choo, Bloomingdale’s, Lexus, Hugo Boss and some major hotel chains.

“What we provide helps our clients more deeply connect with their customers by utilizing the power of scent,” said Ed Burke, director of marketing at ScentAir.

Services typically start at about $100 per month and can increase, depending on factors such as the amount of fragrance needed for a space and the number of locations where the fragrance is used.

Choosing the right fragrance for a business is more than just picking a smell its owner might like.

“The color, decor, the overall aesthetic plays a role,” Burke said, adding that subtlety is key. “Too much of any good thing is too much.”

He said some companies overpower customers, bombarding them with scents. “That is not the way to successfully deliver fragrance in that environment,” Burke said.

Burke said customers in the 12 to 24 age range “like much, much heavier stimulation – strong fragrance and loud music. It’s very dramatic. But it turns off a huge customer base.”

Hotels, which have been using scent branding for the better part of the past decade, typically get it right, according to Burke.

“Now, just about every hotel chain has a signature program,” Burke said. “There is a real critical mass.” Westin Hotels even has its own signature fragrance, White Tea.

At Hotel Monaco in downtown Baltimore, guests are treated to the Kimpton scent – created, like Westin’s, by the hotel chain. The fragrance is described as soft citrus notes that give way to green tea, the spiciness of black pepper and cloves wrapped in a blanket of musk.

At Hotel Monaco, “air machines” are located outside the guest elevators and near the main lobby area.

“It’s part of the arrival experience,” said general manager Ben Timashenka.
