For the Philadelphia Flower Show Horticulture Challenge Classes, all exhibitors start with the same plants and grow them for competition. This is a great opportunity for new and experienced exhibitors to participate in the world’s oldest horticultural event. Attend our free program and learn about the best practices for growing this year's plants.
Only plants purchased from PHS are eligible to be entered. Plants are available to purchase as part of the workshop registration and will be available for pick up after the workshop. Supply is limited. You may purchase one of each type of plant, but each individual registrant must purchase separately.
