2015 Evaluations

Developed by Dr. Claudio Pasian and managed by William Barnhill for 2015, the Ohio State University Cultivar Trials are conducted each year in order to evaluate ornamental bedding and container plants. The objective of these trials is to observe the performance of new and recently introduced cultivated plant varieties under environmental conditions typical of central Ohio.

In 2014, the Cultivar Trials piloted a new app called Digital Evaluator. Designed by Dr. Tim Rhodus, Professor Horticulture & Crop Science, the app can be used on iPhone and iPad devices. While reviewing each plant, volunteers can enters their ratings and comments. Information is saved in the app and then emailed to Dr. Rhodus. Now in its second year, Digital Evaluator is the only evalution option being used to gather data for the trials. The updated app offers some improved user features, for example, a one-button data export, but remains largely the same. As in previous trials, there are four evalation periods during the growing season when data is collected. The website features an interactive table of results, the Gallery of Most Popular plants and how volunteers earned digital badges to recognize their participation and learning to use the Digital Evaluator app.
