Best In Show: 2012 Field Trials Results

Echinacea 'Cheyenne Spirit'

The plants that came through this season’s trials still looking like winners are truly tough. With record-setting temperatures and drought conditions ranging from mild to severe throughout much of the country, new varieties were thoroughly tested.
We asked trial managers from around the country to send us their top performers, as well as the weather conditions during the trial period. Fifteen responded, and the results are shared below.

We did not receive results from any trials in the Northeast or Pacific Northwest. While not every new plant was trialed in every garden, a few cultivars made it onto more than one list of best performers.

Two coleus, Plectranthus ‘Chocolate Covered Cherry’ and P. ‘ColorBlaze Marooned’ were among these, as well as Calibrachoa ‘Superbells Lemon Slice,’ Evolvulus ‘Blue My Mind’ and Begonia ‘Whopper Red With Green Leaf’ and B. ‘Whopper Red With Bronze Leaf.’

The one perennial that made multiple lists was Echinacea ‘Cheyenne Spirit,’ which received the 2013 All-America Selection Flower Award. Several series performed well in multiple trials: angelonia Serenita, catharanthus Cora, verbena Temari, lobularia Stream, petunia Surfinia, geranium Caliente, geranium Calliope, verbena Lanai, plectranthus Under the Sea (coleus)and the petunia Potunia series.
There were many other outstanding performers, varying by region. We’ve included a summary here. For complete trial details and photos, visit GreenhouseGrower.com/November2012.
