The following evaluation scale was used to rate the trials:

 

            5          Excellent (No insects or disease present. Plants uniform in flower form, growth habit, flower color; profuse blooming. Overall, the pinnacle of perfection- hard to imagine any area in which the plant could be better.)
            4          Very good (No insects or disease present. Plants fairly uniform in flower form, growth habit, flower color; fairly profuse blooming. Close to perfect but some areas that could be even better.)
            3          Good (Minimal insect and/or disease damage. Plants fairly uniform in flower form, growth habit, flower color; satisfactory  blooming. Overall, not spectacular, just an average plant.)
            2          Fair (Moderate insect and/or disease damage. Plants poorly uniform in flower form, growth habit, flower color; poor blooming.  Overall, not an appealing plant.
            1          Poor (Extensive insect and/or disease damage. Plants not uniform in flower form, growth habit, flower color; Little to no blooming.  Overall, a plant that you would not want in your garden.
