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. That Trial Ground may be located at a university, a public garden, a commercial greenhouse operation, a breeding station, etc. Once the AAS entries are transplanted into a Trial Ground, the AAS Judges observe and evaluate the garden performance. Those judges, at the end of the trial season, then send their scores and evaluations to the AAS Office and an independent accounting firm for tabulation. Only the best performers (best scores) become AAS Winners.

To view the AAS Judge's bios, please visit the "About Us/Judges" page then click on each judge's name.

Many trial grounds are private locations. To see the AAS Winners, visit an AAS Display Garden.
