As an art student in 1993, Michael De Feo drew a simple bloom that became a familiar and welcome presence in New York after he spent countless nights pasting hundreds of versions of it all over the city's building walls. Twenty-five years later, these flowers have been sighted in more than 60 international cities. De Feo's colorful and lively book reproduces more than 200 of his flower-inspired images and features commentary from a diverse group of people who have supported his often-clandestine work.
