2017 North Carolina State University Field Trial Results

The JC Raulston Arboretum at North Carolina State University in Raleigh, NC, is a 10-acre arboretum and botanical garden with a diverse collection of plants adapted for landscape use in the Southeast. Each year, seed and plug companies submit entries for plant performance evaluation. This year, approximately 360 samples were entered into the trials, which were planted on May 02, 2017.

Trial manager Bernadette Clark says growing conditions this summer started out mild, but by July they turned hot and dry. In the months of July and August, the gardens experienced long periods of temperatures in the 90s, mostly in the low to mid 90s. Three consecutive days of 100+ temperatures occurred July 21 to 23. The precipitation was close to normal for May and June but approximately half of what the gardens typically receive for the months of July and August.

“One of the highlights of the trials this year was the celosia,” Clark says. “The old cockscomb celosias are making a comeback! Beautiful flower colors ranging from yellow to orange to red make these a must have.”
