The Indianapolis Garden Club Flower show is adjudicated under the standards set forth by The Garden Club of America. 

The purpose of a Garden Club of America flower show is three-fold:

• to set standards of artistic and horticultural excellence,
• to broaden knowledge of horticulture, flower arrangement, conservation, and other related areas, and 
• to share the beauty of a show with fellow club members and the public. 

Flower shows combine artistic vision, horticultural mastery, engineering, and sophisticated craftsmanship to create a brief but brilliant display of beauty in time. 

It takes time and effort from many volunteers to organize a flower show. From the chair, to the division committees, the passers to the judges, the tech team to the entrants — each individual contributes to the final experience for visitors.

The GCA Flower Show Committee promotes flower shows throughout The Garden Club of America, provides guidance and encouragement to those planning and presenting GCA flower shows, and reviews each flower show schedule suggesting changes needed to conform to GCA requirements and standards. Special disciplines contributing artistic exhibits in GCA flower shows are encouraged by the Floral Design Committee and the Photography Committee.  

The Judging Committee is responsible for training and selecting flower show judges and maintaining and promoting the standards of excellence set by The Garden Club of America for judging flower shows.
