Testing Roses.
The beds next to the walk are AARS winners. The roses being tested are in the beds behind the winners and are marked with numbers instead of names.
In 1938, the AARS chose Portland for trials for domestic and foreign varieties. This was the very first test garden. In 2012, the AARS was replaced with the American Garden Rose Selections (AGRS) which is a garden trial partnership between the American Rose Society (ARS) and the rose industry.
Portland is one of eleven test sites across the country. This allows for a variety of growing climates and conditions.
Roses are not sprayed with fungicides and do not receive any special care beyond what a home gardener would provide.
Two judges rate the test roses’ performance based on attributes such as disease resistance, vigor, bloom abundance, fragrance, and general impression.
Evaluations operate on a two year cycle; climbing roses are tested for three years.

Portland is also a testing site for the Award of Excellence (AOE) testing program, which is an American Rose Society sponsored miniature rose trial. Other independent rose testing includes Weeks and Star Rose Grower’s trials. IRTG is one of five test gardens nationally for David Austin Roses (near the tennis courts).
