General Introductory Notes and Acknowledgements

The Perennials Trial are located adjacent to the Color Trials at NC State University within the JC Raulston Arboretum (JCRA) in Raleigh. The JCRA is a ten and a half acre site administered by the Department of Horticultural Science and located on 35° 47'N latitude, longitude 78° 42' W, with an elevation of 400'.

Plants to be entered into our trials are received in one of three ways—seeds, rooted cuttings/plugs or finished plants/pot. Virtually all are grown within controlled greenhouse environments prior to placement in protected outdoor structures for hardening off. Plant spacing in the trials is based on the estimated mature size of entrant that fits to a 4' × 4' area or by the number of plants sent. Each entry is evaluated for two complete calendar years, being removed after the spring flush in year three. After the plants are established, they are evaluated for hardiness and landscape performance with ratings regularly taken.

Acknowledgements

We thank the vegetative and seed companies that participate in our trials. The services we provide would not be possible without the cooperation and support of these companies. We appreciate this confidence and trust and we look forward to continuing our partnership.

Lastly, we are thankful to other departmental staff and the volunteers of the JC Raulston Arboretum who assisted in transplanting and maintaining the plants … we couldn't have done it without you all!

Understanding Our Data

Cultural Data

Trials are conducted in amended beds. Prior to planting, beds are fertilized with 10-10-10 granular fertilizer and tilled. All plant material is mulched with composted leaf mulch to a 2"–3" depth after planting. Pre-emergent herbicides are used at the initial planting and repeated each subsequent spring/summer season. Hand weeding is done at all other times. Later in the season, a post-emergent herbicide application along the edge of the beds was done on an as needed basis. An in-ground irrigation system delivers 1"–1.5" of water to the beds each week. Plant height and width measurements (recorded in inches) are taken during the growing season. Data was collected from a representative plant, not the largest or the smallest but an average plant. Dormant plants were cut back in the fall/early winter to clean up the area and reduce overwintering habitat for insects and diseases.

Evaluations

The purpose of our perennials trial is to evaluate the plant material under conditions unique to our location. Our summer growing conditions are typically hot temperatures with high humidity. There is little nighttime temperature relief/recovery; average summer nighttime temperatures can be in the 70s. During our winters we can experience wide and rapid fluctuations in temperatures. Irrigation is required all season.

What do we look for?

  • General Plant Growth – healthy appearance, attractive foliage, uniform growth
  • Flowers – floriferousness, bloom duration, uniform color, does it hold up after a heavy rain
  • Pests and diseases – any visible evidence of damage: distorted or chewed foliage
  • Heat tolerance – do the flowers and plants hold up in the heat, does the flower color fade or stripe
  • Hardiness (survival) – determined (in the spring) by the number of plants that made it through or emerged after the winter

Installation Date

Most entries were planted into their permanent trial location on:

  • 2015 entries on May 12, 2015, and October 20, 2015
  • 2016 entries on May 10, 2016

Average Monthly Precipitation and Temperature

Precipitation Graph - 2016-2017

 

Temperature Grpah - 2016-2017

Our growing conditions during summer 2016 were hot and humid. In July and August, we experienced a prolonged period of temperatures in the 90s coupled with high humidity. Our daytime highs made no meteorological records, but, when coupled with the high humidity, many days were downright brutal with the heat index making the temperature feel in excess of 100°F.

In the month of July, our average night temperature was 72.8°F. The only night when the temperature dipped below 70°F was July 4, when the temperature was 68°F. According to the meteorologists, our high nighttime lows were the 4th highest since World War II.

The hottest temperature (99°F) occurred on July 24 and July 25. The total number of days at or above 90°F was 64, roughly 45% of our growing period. The heaviest rainfall, which was 5.9", occurred on July 17. Rain totals for the summer season exceeded the norm by 11".

The 2016 summer season was challenging due to the frequent rainfall experienced during the early months of the growing period. These conditions were ideal for the development of plant pathogens.

The 2016–2017 winter season was one long roller coaster ride. We experienced low temperatures in the teens to high temperatures in the low 80s. The entire season was made up of rapid cycles of warm temperatures followed by freezing temperatures. There was no gradual transition from cold to warm to cold at any time.

November temperatures were only slightly on the warm side. The first freezing event occurred on November 13 with a low temperature of 28°F. Our "meteorological winter" (December–February) had well above normal temperatures with February breaking historical records. In January, we had seven straight days of below freezing night temperatures with daytime highs in the 30s and 40s. Our coldest night, 11°F, was on January 9. February goes down in the weather books as the warmest in 130 years. We had three days of temperatures 80F or higher!  In March, we had eight back-to-back days of sub-freezing temperatures with daytime highs in the 40s and 50s. Our March average temperatures were lower than those in February.

The rain total for October was 10.45" when Hurricane Matthew devastated our state! November was a very dry month (0.39") making November 2016 the 9th driest since 1887. The reminder of the season was on the dry side, with January and March closest to the norm.
