History of the Festival

The Green Thumb Festival was established by the St. Petersburg Parks Department as an Arbor Day celebration on April 11, 1986 at Boyd Hill Nature Preserve. The concept was introduced by the Parks Director at the time, Litdell “Dell” Holmes, to meet the requirements of the prestigious Tree City USA award, and as a result, the City has been a recipient of the award every year since 1986.

Festival attendance is estimated at 30,000 to 35,000 over the two-day event and more than 200 educational and environmental exhibits and vendors participate. The festival continues to be free of charge.
