Free Admission Wednesday at Queens Botanical Garden - see INFO below. Queens Botanical Garden evolved from the 5-acre Gardens on Parade exhibit showcased at the 19391940 Worlds Fair. Officially opening as The Queens Botanical Garden Society in 1946 after local residents saved and expanded the original exhibit, the Garden remained at the original Worlds Fair site until 1961, when it was moved to its current location on Main Street in Flushing. Among the original plantings taken from the 1939 site are two blue atlas cedars that frame the iconic tree gate sculpture at the Gardens Main Street entrance today. QBG has become a 39-acre oasis in one of New York Citys most bustling and diverse neighborhoods and is unlike any other botanical garden in the world.How to use this page: Click on the plus sign to expand the accordion, located on the right side of each month.
