For the challenge, AAS provided the gardens with recent AAS Winner seeds and plants. The gardens had the option to also incorporate older AAS Winners in their design to give a historical aspect to their display, if desired. Gardens were encouraged to hold educational events (especially appropriate this year) to share the story of All-America Selections and AAS Winners.
Gardens are divided into three categories based on the number of visitors per year:
Category I: fewer than 10,000 visitors per year
Category II: 10,001 – 100,000 visitors per year
Category III: Over 100,000 visitors per year
All-America Selections recognizes and thanks the contest judges who are industry experts in the field of horticulture and landscaping:
Ron Cramer, Retired, Sakata Ornamentals and AAS Former President
Barbara Wise, Marketing, Crescent Garden
Helen Battersby, Garden Writer/Speaker, Toronto Gardens
Penny Merritt-Price, Product Development Manager, Young’s Plant Farm
AAS is proud to announce the following winning gardens from the 2024 Design Challenge:
Category III: Over 100,000 visitors per year
First Place Winner: Green Bay Botanical Garden in Green Bay, Wisconsin
The AAS Landscape design at Green Bay Botanical Garden successfully integrated the STEAM acronym (Science, Technology, Engineering, Art, Math) with a botanical twist. The design featured a spiral garden bed representing the Fibonacci sequence (Math) and reused plastic sculptures connecting to sustainability and the Washed Ashore exhibit (Art). Engineering was demonstrated through various accessible raised beds and an adapted ladder trellis for vertical growing. Technology utilized QR codes on plant labels to link visitors to detailed AAS Winner information. As a cornerstone of the theme, Science highlighted principles of botany, pollination, and nutrition. The immersive garden provided guests with a beautiful and educational experience, ensuring the impact of the planting lingered long after their visit.
Second Place Winner: Boerner Botanical Gardens in Milwaukee, Wisconsin
The trial garden display at Boerner Botanical Gardens featured a distinctive STEAM Train built to reflect the 2025 AAS theme. Utilizing the long bed, the designer constructed a train with each “car” representing a different STEAM discipline, planted exclusively with past and present AAS Winners. The project incorporated a unique train engine and cow catcher built from scrap metal by an Ironworkers Local 8 member. Educational efforts included information cards linking plants to each STEAM concept for visiting school groups. The display proved highly popular, serving as a photo opportunity and educational focal point for both school children and general visitors, generating local news coverage and social media interest.
Category II: 10,001 – 100,000 visitors per year
First Place Winner: Purdue Extension-Marion County Demonstration Garden in Indianapolis, Indiana
Extension Master Gardener volunteers, in collaboration with the local Purdue University Extension office, planned, planted, and maintained the Purdue Extension Marion County Demonstration Garden. The garden achieved a new daily visitor record of 1,039 people during the Indiana State Fair, with guests seeking design ideas and solutions to gardening issues. New AAS Winners like Petunia Dekko Maxx Pink and Pepper Pick-N-Pop Yellow were visitor favorites. The garden prominently featured a “Living Classroom” banner and dedicated signage to illustrate the STEAM curriculum. This included a Pi Trail (Math), an F1 Hybrid explanation (Science), a Flower Tower demonstration (Engineering), and QR codes (Technology) for plant lists and construction guides, effectively turning the display into a popular and engaging educational experience.
Second Place Winner: McCrory Gardens in Brookings, South Dakota
McCrory Gardens titled its 2025 AAS Design Garden, “The Art of Curiosity in the Pigment Garden: Art, Science, and Horticulture Converge.” Inspired by a conference presentation, garden staff created a feature showcasing AAS Winners and other species capable of producing natural dyes. Every plant label included its scientific name, dye color, and the specific plant part used. The design incorporated a wide range of AAS Winners, from vintage classics to modern selections, including Marigold ‘Mango Tango’ and Basil ‘Dark Opal.’ Educational signs explained the dye extraction process, highlighting the intersection of Horticulture, Science, and Art. Visitors expressed fascination and surprise at the diverse potential of the pigment garden.
Third Place Winner: Horticultural Art Society Demonstration Garden in Colorado Springs, Colorado.
The Horticultural Art Society (HAS) successfully integrated STEAM principles into their public garden by developing structured, interactive educational activities. The design included a Garden Library with an AAS Infographic and multi-level Scavenger Hunts, alongside raised plant troughs demonstrating square foot and companion gardening (Math/Science) and water-saving irrigation (Engineering). To promote ecological awareness, a functional worm box and a pollinator house offered hands-on learning. Art was emphasized through recycled material sculptures and creatively painted elements. These dynamic, educational features have notably increased visitor engagement, especially among young children, promoting sustainable living and environmental stewardship throughout the community.
Category I: fewer than 10,000 visitors per year
First Place Winner: Penn State Ext Lancaster County Master Gardeners’ Idea Gardens in Mannheim, Pennsylvania
The Penn State Extension Master Gardeners’ Idea Gardens successfully incorporated STEAM concepts into their 2025 display, featuring numerous educational signs with AAS branding. They hosted four well-attended Open Houses and various activities, including creating seed balls and planting in paper pots, alongside a “Garden Quest” for adults. Two visiting art associations were inspired to paint the gardens, adding to the visual appeal. AAS Winners, including the grand Sunflower ‘Concert Bell’, were strategically planted for color and height. All AAS produce was donated to the “Adopt-A-Pantry” food program. Approximately 1,700 known visitors toured the gardens, enjoying the engaging activities and the educational display of AAS and STEAM concepts.
Second Place Winner: Kansas State Univ Horticulture Research and Extension Center in Olathe, Kansas
The Johnson County Extension Master Gardeners at the K-State Olathe Horticulture and Research Center designed their AAS Display Garden to be a demonstration and teaching garden centered on the STEAM theme. A primary goal was creating an easily accessible, self-guided tour using QR codes and a video presentation, limiting verbiage and maximizing photos for all ages. The design successfully incorporated all five STEAM elements, highlighted by paintbrush sculptures and a central color wheel. Visitors and fellow Master Gardeners praised the healthy plants, overall aesthetic, and the integrated use of QR codes and AAS plant markers, allowing them to fully understand the educational application of STEAM within the garden space.
Third Place Winner: Community Arboretum at Virginia Western Community College in Roanoke, Virginia
Horticulture student interns at the college developed the AAS garden design, unifying the STEAM theme through the Fibonacci Sequence. The sequence (1, 1, 2, 3, 5, 8, 13, 21, 34) was visually represented by a spiral of zinnia cultivars. Each numerical block corresponded to a STEAM discipline, such as five blocks for the Science section, which depicted a plant cell. Engineering featured a hexagon-shaped bed representing a honeycomb, while the Art section was shaped like an artist’s pallet. Technology displayed cucumbers on trellises, symbolizing biomimicry. Visitors were particularly impressed by the detailed interpretation of the Fibonacci Sequence, validating the student-led planning, preparation, and installation of the complex display.
