No one knows how to brighten a random passerby's day quite like Lewis Miller. The highly celebrated Floral Designer and creator of the Flower Flash - an overnight fresh flower fantasy that pops up in the most unexpected of places - is at it again.

In partnership with Fifth Avenue Association, Lewis Miller Design is gifting New Yorkers four beautiful excuses to smile today, a most wonderful way to honor the anniversary of 9/11. A smokestack in the middle of the street bubbles up with daisies and marigolds, a huge ombre flower heart leans against the street pole at 55th, a bus stop sits cheerfully draped with sunflowers, and a bench by the Pulitzer-Fountain transports its sitter to a magical secret garden.
