The Xi’an Scent Garden, commissioned for the 2011 Xi’an World Horticultural Exposition, delights all the senses while favoring smell. Its terraced pine groves and beds of rosemary and thyme build and sustain a unique olfactory world.

The local conifers create an olfactory, visual, and tactile connection to Xian. Motion sensor-activated scent poles diffusing plant extracts complement these fragrances with exotic accents evoking other locales to create an olfactory map of China. Together the scents marry nature with artifice. Scent Garden is both spectacular and intimate. Its constellation of glowing scent poles create an iconic image that denotes the garden as a public space, while its nuanced sensory readings provide sheltered and individual experiences.

The scent poles double as light fixtures. They consist in stainless tubes with integrated scent cartridges and LED lights. The Scent is diffused naturally by the breeze or more promptly for approaching visitors by a sensor activated fan. The light intensity varies with the velocity of the wind. It is modulated by a wind sensor at the top of the pole. The lighting’s dynamic response translates the scent propagation pattern into a visual phenomenon.
