Spring is coming. And what better way to usher it in than flowers For over 70 years, Macys Department Store has been celebrating the season with an extravagant exhibition of flowers and lush gardens. This years celebration will be in full bloom for two weeks from March 26 to April 9 at its three flagship locations, including Herald Square in New York City, State Street in Chicago, and Union Square in San Francisco. This years gardens will imagine a colourful world based on the theme, the Carnival.
