As spring arrives, the region’s events calendar ratchets up, enticing you out of winter hibernation.

Catch early blooms at Longwood Gardens’ Orchid Extravaganza and the Flower Power-themed Philadelphia Flower Show. Eat and drink the day away during the Italian Market Festival and Philly Beer Week. Or dive into spring cleaning before sprucing up your house with finds from the Philadelphia Antiques and Art Show.

This year, the city will spend two weeks celebrating the bicentennial of Walt Whitman’s birthday (May 31). But don’t forget annual festival favorites, like New Hope Celebrates PrideFest, South Street Spring Festival, and the 9th Street Italian Market Festival.

Pay particular attention to the Entrance Garden, featuring displays from the Interflora World Cup, a prestigious competition that pits florists from 23 countries against each other in design challenges (which Flower Show audiences can watch March 2 and 3).
