In 1940 the International Rose Test Garden became an official testing site for the All-America Rose Selection (AARS), a Chicago-based non-profit association of rose growers dedicated to the introduction and promotion of exceptional roses. Since 1938 the AARS seal of approval has graced new rose varieties that have performed the best in the test gardens located throughout the country and representing all climate zones. 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 in 24 rose test gardens nationwide.
Free tours of the rose garden are led by trained volunteers at 10:00am and 1:00pm on Tuesdays, and 1:00pm on Saturdays & Sundays. Meet at the sign outside the Rose Garden Store. Donations gladly accepted.
