About AAS Winners

The All-America Selections Trialing Process

All-America Selections National and Regional Winners have been tested for garden performance by a panel of expert judges. Varieties that perform best over all of North America become AAS National Winners. Entries that performed particularly well in certain regions are named AAS Regional Winners. The AAS Winners offer gardeners reliable new varieties that have proven their superior garden performance in Trial Grounds across North America, thus, our tagline of “Tested Nationally and Proven Locally®”.

When you purchase an AAS Winner, you know that it has been put through its paces by an independent, neutral trialing organization and has been judged by experts in their field. The AAS Winner label is like a stamp of approval. AAS Winners are bred and produced without using genetic engineering, commonly referred to as genetic modification or GMO.

Who Determines an AAS Winner?

Independent AAS Judges determine the AAS Winners by judging and scoring the entries. Judges look for significantly improved qualities such as earliness to bloom or harvest, disease or pest tolerance, novel colors or flavors, novel flower forms, total yield, the length of flowering or harvest and overall performance. In the last ten years, an entry needs to have at least two significantly improved qualities to be considered by Judges for an AAS Award.

The Judges score each entry from 0 to 5 points, with 5 being the highest. Only entries that meet scoring criteria is considered for a possible Award. New, never-before-sold varieties with proven superior qualities are announced three times each year as AAS Winners.

AAS Trial Grounds

An AAS Trial Ground is one of the most important elements in the process of declaring AAS Winners. A Trial Ground is a location where a professional horticulturist works in their field and where the AAS entries are planted next to comparisons or scientifically speaking, controls. Once the AAS entries are transplanted into a Trial Ground, the AAS Judges observe and evaluate the garden performance. At the end of the trial season, the judges send their scores and evaluations to the AAS Office for tabulation.

Only the Best Become AAS Winners

Only the best garden performers (best scores) become AAS Winners. Once new varieties are announced as AAS Winners, they are available for immediate sale and distribution. Home gardeners will find seeds available from their favorite catalog or online seed source or as young plants at their favorite garden retailer.

The AAS Judges

AAS judges are located in geographically diverse areas all over the U.S. and Canada. Since its inception, AAS has relied on the expertise of our volunteer judges to be the eyes and evaluators of our flower and vegetable entries. Without them, we could not confidently say that we have experts in the field who are trialing these new varieties to determine which entries are worthy of an AAS Award. Our judges work for companies such as breeders, brokers, growers, garden centers, public gardens or land grant universities. Their role is or includes trial management for their respective organizations.

If press or media would like to contact or interview one of our AAS Judges, please contact the office for an introduction.
