Rose Trials

American Rose Trial for Sustainability or A.R.T.S.®

This trial includes 20 shrub roses in 3 replicated blocks, equaling 60 plants total, which were planted and watered for a few weeks to establish them. After that, the shrub roses received no supplemental water, no fertilizer, no pesticide treatment, and no winter protection. The idea is to find beautiful flowering roses that require very minimal care and are not susceptible to insects and disease. These roses are trialed for two years (after which a new group is planted) and evaluated monthly by our horticulture team. The A.R.T.S. ® trial is located to the east of the Magnolia Grove behind the Matthew Schmidt Garden. Green Bay Botanical Garden is one of 11 national sites in the A.R.T.S. ® program. The Look for A.R.T.S. ® winning roses in garden centers in the upcoming years.

Earth-Kind® Rose Trial

This trial includes 20 hybrid tea and floribunda roses in 4 replicated blocks, equaling 80 plants total. These roses are treated similarly to the A.R.T.S. ® roses except they get mulched for winter protection. These roses are trialed for three years (after which a new group is planted) and evaluated monthly by our horticulture team. The trial’s goal is to provide homeowners and retailers with trouble-free hybrid tea and floribunda roses that look great with minimal care. The Earth-Kind® rose trial is located to the east of the Magnolia Grove behind the Matthew Schmidt Garden. Green Bay Botanical Garden is the only northern test site for this trial in the country.
