Non Technical Summary
The green industry is the second largest agriculture sector in Maryland, however, the lower shore region only represents a small portion of horticulture sales and services (3%) in Maryland. Developing a university trial garden would provide information and services to enhance the profitability of the lower shore region's green industry, and improve the quality of life for residents living in this area. Trial gardens enhance ornamental horticulture by providing commercial plant growers, plant breeders, retailers, and the home gardener with unbiased evaluations of plant cultivar performance in the landscape under local growing conditions.

Goals / Objectives
The main objectives of this project are: 1) to design and develop a university trial garden at the UMES Agricultural Experiment Station, 2) to train undergraduate and graduate students on research and plant evaluation protocols, and 3) to make the data obtained from the trials readily available to landscape professionals, greenhouse growers, retailers, and consumers through education and outreach activities.
Project Methods
The university trial garden will evaluate 80-100 new flower varieties and compare their landscape performance to traditional flower varieties. Popular bedding plants will be evaluated in the garden. Seed companies will donate seeds and/or rooted cuttings of new, unsold flower varieties. The seeds and rooted cuttings will be planted in the greenhouse according to production procedures, and then placed in the trial garden in late May. The plants will be transplanted in the flowerbeds and maintained according to accepted principles of maintenance. For annuals, data will be collected on twelve plants per entry two weeks after installation and every two weeks thereafter until October. Plant varieties will be compared and evaluated for landscape performance based on selected plant characteristics such as insect and disease resistances, weather tolerance, growth rate, flower color and number, fragrance, and overall foliage leaf health. Based on a visual assessment of those characteristics, the flower varieties will be rated on a single numerical rating from 0 to 5; with 5 being optimum and 0 indicating that the plant has died. The ratings will be used to generate time performance graphs per entry. The graphs will provide an in-depth understanding of how a plant performed from spring to fall. Annuals will be evaluated for one year. Perennials will be maintained and evaluated the same as annuals; however, data will only be collected when flowers are present. The actual dates for beginning of flowering, peak flowering time, last flower date, and mature height will also be recorded. Perennials will be evaluated for three years. A photo-essay will be developed throughout the trials for both annuals and perennials. This project will provide undergraduate students with hands-on experiences by working in a greenhouse and field setting. The students will be responsible for starting the flower varieties from seed and/or rooted cuttings, caring for them in the greenhouse, transplanting the plants into the field, making bi-monthly plant evaluations, and the daily maintenance of the garden. Once all the data has been collected and analyzed, the students will be responsible for creating charts, graphs, and tables to report on the research findings. The students and team members will develop publications that will be distributed through the Maryland Cooperate Extension and other associations within the green industry on the lower shore region. The trial garden will be open to the public everyday from early morning until dusk. An open house will be scheduled for landscape professionals, greenhouse growers, retailers, and home gardeners. The outcome of this study will be made available in various forms (brochures, handouts, reports) to the Maryland Cooperative Extension and published in an international refereed journal. An extension agent has also agreed to help us make contact with the nursery, greenhouse, and landscape professionals to distribute the research findings.

OUTPUTS: The University Floral Trial Garden was created in June 2007 to provide information and services to enhance the profitability of the lower shore region's green industry and improve the quality of life for residents living in this area. The green industry is the second largest agriculture sector in Maryland, however, the lower shore region, which includes Dorchester, Somerset, Wicomico, and Worcester counties, only represents a small portion of horticulture sales and services in the state. The University Floral Trial Garden was developed to enhance ornamental horticulture by providing growers, retailers, and home gardeners with unbiased evaluations of new plant varieties and how they perform in the landscape under local growing conditions. Trial gardens evaluate which plants can thrive in the local climate and ultimately determine which new plants to introduce to the local greenhouse and landscape industries. The university trials were conducted every summer from 2007-2011, and a total of 368 plants were evaluated. Ball Horticultural Company, PanAmerican Seed Company, Ball FloraPlant, Selecta First Class, Inc., and Athens Select were the seed companies that participated in the trials. The trial garden was open to the public every day from early morning until dusk. Open houses and an Ag Field Day also provided opportunities for the local green industry, gardeners, and the local community to visit the trial garden and learn about the annual bedding plants being evaluated. Two posters were presented at the American Society for Horticultural Science Annual Conference. Each year the trial garden results were shared with the stakeholders who participated in the trials. The trial results were also posted on the University Trial Garden website- http://www.umes.edu/Agriculture. PARTICIPANTS: Ball Horticultural Company, PanAmerican Seed Company, Ball FloralPlant, and Athens Select are the companies that participated in the trial. Mrs. Ginny Rosenkranz, Maryland Cooperative Extension commercial horticulturist and consultant on the project, conducted the observations involving the insect and disease resistance of the plants and helped to distribute the trial results to local nurserymen, landscapers, and master gardeners. TARGET AUDIENCES: Stakeholders (seed companies), commercial plant growers, plant breeders, retailers, and the local home gardener are the target audiences for this effort. PROJECT MODIFICATIONS: Not relevant to this project.

Impacts
The UMES trial garden has been highly publicized in the local news on three separate occasions fulfilling one of its goals to highlight the programs and research being conducted within the UMES Agricultural Experiment Station. In 2009, the UMES Floral Trial Garden became an All-America Selections (AAS) Display Garden. Becoming a registered AAS display garden greatly benefits the profitability of the green industry in the lower shore region and provides visibility, credibility, and pride to the university and the departmental programs. The trial garden has also greatly benefited the stakeholders/seed companies that participate in the trials. They share the results to the growers in the Maryland area so that they can better identify top performing products to grow and have available for landscape and home consumers in the Maryland region. They also share the results with the rest of their sales team, marketing/advertising, customer service, seed and vegetative product supply departments and their product managers and breeders who can also make recommendations to those growers, garden writers, and others who are important leaders in the horticulture industry on the Atlantic coast. The trial results are also used to develop additional varieties that will perform well under the east coast growing conditions. Undergraduate and graduate students have gained practical experience in research and plant evaluation protocols, as well as experience in poster and oral presentations. The trial garden is also used as a living laboratory, which enhances our academic courses in the Department of Agriculture, Food, and Resource Sciences.

OUTPUTS: The 2010 UMES Floral Trial Garden began June 2010. Ball Horticultural Company, PanAmerican Seed Company, Ball FloralPlant, and Athens Select are the companies that participated in the trial. Seeds were received in March 2010, germinated in a plant growth chamber, and then placed in a greenhouse. Cuttings were received April 2010. The plants were watered and fertilized as needed and maintained according to accepted principles of maintenance. Plants in the greenhouse were fertilized with liquid Miracle Gro. Thirty-eight flowers were planted in the trial garden the week of June 1, 2010. Six plants from each flower variety were evaluated, by three evaluators, on a visual assessment of characteristics every two weeks from June to August. The flower varieties were rated on a single numerical rating from 1 to 5, with 5 being optimum and 1 indicating that the plant had died (see below). The average of the evaluators' assessment was determined. The plants were watered by hand for the first few weeks of the trials. In the previous years, a sprinkler irrigation system was used for the first few weeks to get the plants established. As a result, some plants received too much water and experienced root rot and others did not receive enough water. Due to the hand watering, the plants performed much better in the trials. Hand weeding was performed throughout the trial. It was extremely hot and humid this summer especially in July. We had several heat waves over the summer with temperatures over 100o F. The flowers were fertilized with Miracle Gro Liquafeed All Purpose Plant Food (12-4-8) once in June and once in July. The commercial horticulturist, a consultant on the project, conducted the observations of insect and disease resistance in the plants. Height and width data were also collected. All American Selections Flower Display Garden: In 2009, the university trial garden became a registered All America Selections (AAS) Flower Display Garden. Sixteen AAS winners from 2006-2010 were also displayed in the 2010 Floral Trial Garden. Dissemination of Results: The trial garden results were shared with the seed companies that participated in the trial. The trial results were also posted on the University Trial Garden website- http://www.umes.edu/Agriculture. PARTICIPANTS: Ball Horticultural Company, PanAmerican Seed Company, Ball FloralPlant, and Athens Select are the companies that participated in the trial. Mrs. Ginny Rosenkranz, Maryland Cooperative Extension commercial horticulturist and consultant on the project, conducted the observations involving the insect and disease resistance of the plants and helped to distribute the trial results to local nurserymen, landscapers, and master gardeners.

Ball Horticultural Company, PanAmerican Seed Company, Ball FloralPlant, Selecta First Class Inc., and Athens Select are the companies that participated in the trial. Seeds were received in March 2009, germinated in a plant growth chamber, and then placed in a greenhouse. Cuttings were received April 2009. The plants were watered and fertilized as needed and maintained according to accepted principles of maintenance. Plants in the greenhouse were fertilized with liquid Miracle Gro. Seventy-two flowers were planted in the trial garden the week of June 1, 2009. Six plants from each flower variety were evaluated, by three evaluators, on a visual assessment of characteristics every two weeks from June to August. The flower varieties were rated on a single numerical rating from 1 to 5, with 5 being optimum and 1 indicating that the plant had died (see below). The average of the evaluators' assessment was determined. Although a sprinkler system was available, it was only utilized for the first few days after planting. Maryland had a lot of storms and rain activity during the month of June. Due to the heavy precipitation during the first few weeks in June, the plants were really stressed. Most of the plants had not recovered transplant shock and were also affected by too much moisture along with hot temperatures. The flowers were fertilized with Miracle Gro Liquafeed All Purpose Plant Food (12-4-8) on June 11, 2009, and July 2, 2009. The commercial horticulturist, a consultant on the project, conducted observations involving the insect and disease resistance of the plants. Height and width data were also collected. Dissemination of Results: The trial garden results were shared with the participating seed companies that participated in the trial, nurserymen, landscapers, master gardeners, and the local residents that attended the Ag Field Day held on September 12, 2009.

OUTPUTS: The 2008 UMES Floral Trial Garden began June 2008. Ball Horticultural Company, PanAmerican Seed Company, Ball FloralPlant, Athens Select, and USDA, ARS, are the companies that participated in the trial. Seeds were received in March 2008, germinated in a plant growth chamber, and then placed in a greenhouse. The plants were watered and fertilized as needed, and maintained according to accepted principles of maintenance. Plants in the greenhouse were fertilized with liquid Miracle Gro. Four plants were shipped through the mail from Athens Select. The plants were extremely dry when they arrived and three of them did not perform well throughout the trail evaluations. They did, however, start to flourish after the evaluations. The flowers were planted in the trial garden the week of June 5, 2008. A three-month slow release fertilizer (10-10-10) was incorporated into the soil during planting. Nine plants from each flower variety were evaluated, by three evaluators, on a visual assessment of characteristics every two weeks from June to September. The flower varieties were rated on a single numerical rating from 1 to 5; with 5 being optimum and 1 indicating that the plant had died (see below). The average of the evaluators' assessment was determined. Maryland had a heat wave the second week after the plants were planted in the garden. Most of the plants had not recovered transplant shock and were affected by the heat wave. The flowers were fertilized with Miracle Gro Liquafeed All Purpose Plant Food (12-4-8) on June 19, 2008. Maryland also had a lot of storms and rain activity during the month of June. The Commercial Horticulturist, a consultant on the project, conducted the observations of insect and disease resistance of the plants. Height and width data were collected on August 18, 2008. Dissemination of Results: The trial garden results were shared with the participating seed companies that participated in the trial and the local residents that attended the 2008 open house.

OUTPUTS: The UMES Floral Trial Garden was created in June 2007 to provide information and services to enhance the profitability of the lower shore region's green industry, and improve the quality of life for residents living in this area (Dorchester, Somerset, Wicomico, and Worchester counties). The University Floral Trial Garden was developed to enhance ornamental horticulture by providing growers, retailers, and home gardeners with unbiased evaluations of plant cultivar performance in the landscape under local growing conditions. The function of the trial garden is research, education, outreach, and evaluation and introduction of new plant cultivars to the greenhouse and landscape industries. Undergraduate and graduate students also gained practical experience in research and plant evaluation protocols. The trial garden is used as a living laboratory to enhance our academic courses in the Department of Agriculture, Food, and Resource Sciences, and to attract the campus and local community to the university for leisure recreation, open houses, and educational and outreach initiatives. The university trial garden was open to the public everyday from early morning until dusk. Three seed companies participated in the 2007 floral trials. Seeds were received in early March, germinated in a plant growth chamber and then placed in a greenhouse. Rooted cuttings were received in early May. The cuttings were transplanted and grown in the greenhouse. The plants were watered and fertilized as needed, and maintained according to accepted principles of maintenance. Ninety-seven flowers were planted in the trial garden the week of June 5, 2007. A 3-month slow release fertilizer (10-10-10) was incorporated into the soil during planting. Each plant was evaluated, by 3 evaluators, on a visual assessment of characteristics every two weeks from June to September. The flower varieties were rated on a single numerical rating from 1 to 5, with 5 being optimum and 1 indicating that the plant had died. The average of the evaluators' assessment was determined. A sprinkler irrigation system was utilized for the first three weeks. Hand weeding was performed throughout the trial. Dissemination of Results: The trial garden results were shared with the three seed companies that participated in the trial. A University Trial Garden website was created to display the trial results. The overall rating and a time performance graph are displayed for each plant. A photograph of each plant is also displayed with its rating. A copy of all of the ratings is also available on the website. The link to the website was also sent to the Maryland Cooperative Extension to be place on the Home Gardner website. Two research posters were presented at the American Society for Horticulture Science 2008 Annual Conference in Orlando, Florida. One poster presented the research data from the entire floral trials and the other poster presented the data obtained for the open house. PARTICIPANTS: Corrie Cotton is the PI on the project.
