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:

• 2017 entries on May 16, 2017
• 2018 entries on May 24, 2018 (additional Syngenta Flowers planted October 30, 2018)

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

The growing conditions during summer 2018 were warm, nothing record breaking, yet persistent heat. The rain was significant, but not record breaking (until the fall). The precipitation was normal for May but very dry in June. July was slightly wetter than normal with August and September receiving more than twice the usual amount of rainfall.

We did not have any 100° days. However it was hot. There were some miserable days. We had fifty-six, 90+°F days with the warmest being 99°F seen on June 19. Our longest stretch of 90+°F days occurred early in the season, from June 17 through June 25. Our greatest amount of rainfall, 4.5", occurred on August 20. In September, Hurricane Florence dropped over 7” of rainfall over a period of several days. Many of the plants didn't survive the saturated soils and of those that did survive the following period of high heat negatively impacted them. 

We had two hurricane/tropical storms (Florence (September) and Michael (October)) that affected us this year, making 2018 the wettest year on record for our area.  At times, we thought we would never dry out.

The first freezing event occurred on November 11 with a low temperature of 28°F. Our first snow occurred on December 9 (7"). That event tied for the area's third highest daily snowfall amount in a December. We had our entire winter average in one day!

Our "meteorological winter" (December–February) had above normal temperatures. Our longest stretch of freezing temperatures occurred early in the season, from December 6 through December 14. Our coldest night, 18°F, was on January 31.

Overall. the last half of 2018 and the first half of 2019 were very wet much to the detriment of the trials. The following are the greatest amount of rainfall received in one day followed by the monthly total: August (4.5"/10.0"), September (2.15"/10.2"), October (2.87"/4.77"), November (3.67"/7.11"), December (1.63"/6.86"), January (1.18"/3.28"), February (0.99"/4.29"), March (1.83"/3.03"), and April (2.25"/7.10").
