Colorful tulips to take over SF’s Union Square

If you want to experience a dazzling floral spectacle and take some of it home with you, mark your calendar for the annual Flower Bulb Day, sometimes called Tulip Day.

On March 21, the 80,000 tulips that were planted in Union Square, creating one of the city’s most photogenic and extravagant pop-up exhibitions, will be given away on a first-come, first-served basis.

Visitors are invited to handpick their own bouquet of fresh tulips — usually six to eight stems per person — and take them home for free.
