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:

  • 2021 entries on May 11, 2021
  • 2022 entries on May 09, 2022

Temperature Graph - 2022-2023

The 2022 summer season growing conditions were hot with little rain. The rain was scarce but when it did rain, it often was very heavy. Our greatest amounts of rainfall occurred on August 12 (3.12") and September 30 (4.07"). This season there were few breaks from the heat, making this summer our third warmest on record. Our first 90-degree days occurred on May 19, two days after planting! July had the most 90°+ days at 26 days. During mid-August, we had a short break in the heat (temperatures in the 80°s) but the heat flipped back on after that brief tease. We had one 100° day on June 14.

A recap of our winter: October was cool for us. We had our first frost event on October 19. October was extremely dry (0.59"). Then the heat returned. November was our fifth warmest November since 1887. We had temperatures in the 80s, November 5 (82°F), 6 (80°F), and 7 (81°F). This month also saw our first freeze on November 18 (24°F). This event was part of a multi-day period of freezing nights. Two of our heaviest rainfalls occurred in November, on November 1 (1.72") and 28 (3.31"). December started out warm but the second half was very cold. In fact, the nighttime low for the later part of the month never got above freezing with the exception of December 31 (41°F). The coldest night of the season was 15°F on Dec 24.

January was warm and wet. We had 2 days in the 70s, January 4 and 19. Which was a bit unusual as our coldest weather normally comes toward the end of January. We had 9 days in the 60s. During this month, we were below freezing on 10 nights. We had a trace accumulation of snow (1-hour long event) on Jan 14. Other than this flirt with snow, our winter was snow-free. No relief in Feb from the warmth. We broke an all-time record on February 23 when we reached 85°F!

March was warm with the exception of one week in the middle of the month. On March 14, an arctic air mass slammed into Raleigh. This late season event brought freezing temperatures, four nights out of seven (lowest was 30°F). Our warmest day in the month was 88°F on March 24. It was a dry month. April on the other hand was wet. Heavy rainfalls occurred twice, on April 9 (2.85") and 16 (1.45").
