Children's Plant Fair

Child Holding a Potted Plant

Children learn the responsibility of caring for a plant and discover the self-satisfaction in raising something. Most importantly, gardening is a great way for parents and children to bond in the great outdoors.

Children in pre-school to fifth grade can participate in the fair by:

Step 1: Growing one or more plants or trees in a container at home.

Step 2: Bringing their plant and registration card for “show and tell” to the festival between 10 a.m. and 3 p.m. on Saturday or Sunday. Children show their plant and give information about growing plants. Each participant will receive a goody bag. The first 100 participants each day will also receive a free T-shirt.

Flower Show

The Garden Club of St. Petersburg displays their creativity through juried floral designs and crafts representing gardens from around the world. Exhibits are designed with a new theme each year.

The public is invited to vote for the best of show in both the horticulture and floral design category. Also, local middle school students showcase their science fair entries.

Judging occurs the Friday before the festival and awards are given to the winners at the festival on Sunday at 3 p.m. inside Walter Fuller Recreation Center. All judges are from clubs within the Florida Federation of Garden Clubs District VIII and use standards set by the National Garden Clubs, Inc. For more information on the Garden Club, visit

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.
