What do you do with leftover flowers when you’re a successful floral designer with a booming business? Well, you create gorgeous flower art across New York City, of course.

NYC-based florist Lewis Miller calls his works of colorful art “Flower Flashes.” To pull them off, he and his team arrive at a location before the sun is up and build an oversized flower arrangement using blooms recycled from other events.

Miller says he and his team can set up the gorgeous installations in as little as 10 minutes – and there’s no telling where they’ll be next.
