International Rose Test Garden

The primary purpose of this garden is to serve as a testing ground for new rose varieties. The City of Portland Gold Medal Awards are issued annually to the best introductions. The first "Gold Medal" rose award was given in 1919, making it the oldest rose testing program of its kind in the United States. Portland is the only North American city to issue such awards. These award winning varieties are planted in the Gold Medal Garden.

The terrace above the Shakespeare garden was originally planted in old garden roses. By 1959, so many Gold Award roses had crept into the terrace that it became known as the Gold Award Garden and the old garden roses were moved to another area of the garden.

With the support of the Portland Rose Society, today's Gold Medal Garden was constructed in 1969 commemorating 50 years of Gold Medal awards in the City of Roses. In 1991, the Portland Rose Society donated the garden's gazebo, a popular spot for weddings and a vantage point from which to view the roses.

The International Rose Test Garden is also one of 24 official testing sites for the internationally respected All-America Rose Selections (AARS). The All-American Rose Selections is a non-profit association of rose growers and introducers dedicated to the introduction and promotion of exceptional roses. Since 1938 the AARS seal of approval has graced outstanding new rose varieties that have performed the best in the test gardens located throughout the country and representing all climate zones. AARS testing began here in Portland in 1940.

Roses currently under test in the garden are not named but are designated only by a number. The new varieties are submitted by the hybridizers to the AARS, who then distributes them to the test gardens identified only by their code number. Four plants of each entry are evaluated for two years on 14 different characteristics consumers desire in a garden plant including plant habit, vigor, disease resistance, color, flower production, form, foliage, and fragrance. About 200 rose cultivars are under test each year.
