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:

  • 2016 entries on May 10, 2016
  • 2017 entries on May 16, 2017

The best way to really evaluate our trials is to come in person. The JCRA is open 365 days a year.

Average Monthly Precipitation and Temperature

Precipitation Graph - 2016-2017

 

Temperature Grpah - 2016-2017

Summer 2017 started out mild but by July turned hot and dry. In the months of July and August, we experienced long periods of temperatures in the low to mid 90s.

The hottest temperature (101°F) occurred on July 22. We had three consecutive days of 100+ temperatures that occurred from July 21 to July 23. July 2017 was the 6th warmest overall for Raleigh since 1887. The total number of days at or above 90°F was 50, roughly 33% of our growing period.

The heaviest rainfall, which was 2.1", occurred on June 17. The precipitation for May and June was close to normal but for the remaining summer months we had approximately half what we typically receive.

Winter 2017–2018 was a season of flux. We experienced low temperatures in the low teens to high temperatures in the high 70s. There was no gradual transition from cold to warm to cold at any time.

The first freezing event occurred on November 11 with a low temperature of 30°F.  We had two snows, January 4 (1.5 inches) and January 18 (6.0 inches).

Our "meteorological winter" (December–February) had above normal temperatures. Our coldest night, 10°F, was on January 6. In January, we had eight back-to-back days of sub-freezing temperatures (7 of which had lows between 10°F and 18°F) with daytime highs in the very low 30s. The all-time record for number of hours at or below freezing was shattered during this cold spell. The old record was 157 hours and the new record is 200+ hours. Our March average temperatures were lower than those in February.

The rain total for October was 5.9".  November and February were dry months, both receiving less than 2" of rain. The reminder of the season was on the dry side, with March closest to the norm.
