All-America Selections (AAS) cultivates a vast network of partnerships across the horticultural landscape, collaborating with diverse organizations and companies throughout the distribution chain to “grow and show” AAS Winners.
This collaborative effort ensures that these exceptional plants reach gardeners nationwide. From the initial breeding and trialing stages to the final display in public gardens, each partner plays a crucial role. This network comprises several distinct garden types, each serving a unique purpose in the AAS mission. This article is designed to illuminate the characteristics and contributions of each of these vital garden types, providing a comprehensive understanding of how AAS Winners are brought to life.
All-America Selections Trial Gardens/Trial Grounds

Behind every AAS Winner is a dedicated team of volunteer judges and a network of unique gardens: AAS Trial Grounds. These are the proving grounds where new plant varieties are put to the ultimate test. At locations across the country, from bustling seed companies to tranquil university gardens, judges cultivate new entries alongside established varieties, meticulously observing their performance. Each AAS entry is known only by a code, ensuring unbiased evaluation. Over the course of the growing season, judges score each entry based on a range of criteria, and these scores determine which plants rise to the top and earn the prestigious AAS Winner designation.
