The main attraction at the show is the exhibits, which range in size from garden displays with elaborate landscaping to individual and club entries of a prize horticultural specimen. Each year there is an official theme (2008: Jazz It Up!) which serves as the inspiration for most exhibits. The exhibits are submitted for judging in many categories, some of which are highly competitive.
The competitive classes often have an assigned theme, related to the overall show theme. In 2007, one of the Pressed Plant Material (i.e. dried flower pictures) themes was "..incorporating a Celtic Knot.". The first weekend's Medium Niche theme was Wish You Were Here "Exhibitors will be sent Irish postcards for inspiration. A copy of the postcard will be mounted next to the exhibit." Entrants for that class typically have a mockup of the niche at home, where they practice assembling and lighting their entry in the months preceding the show. In a Challenge class, entrants bring only pruning shears, and must use show-provided materials to interpret a theme within a limited amount of time. Three typical Horticulture classes are 142: Clivia, flowering. Pot 8" or under, 143: Clivia, flowering. Pot 8"-10", and 144: Clivia, foliage. (There was also a Clivia entered in 2007 under Exceptional plants 10-20 years old, to be judged against “perfection” for their species/cultivar.)
There are also many educational presentations and talks related to landscaping and horticulture.
