The garden is open to public daily from dawn until dusk; admission is free. Each spring, thousands of annual flowers are planted throughout garden, and are on display from late May or early June through October (depending on regional weather conditions). Hardy trees, shrubs, grasses and garden structures are available for viewing year-round. Visitors are encouraged to take note of the new varieties, and observe and study growth habits, tolerances and visual characteristics of the many varieties on display.

Horticulture staff at the West Central Research and Outreach Center (WCROC) focus on research-based projects in the areas of annual and perennial flowers, chrysanthemums, small fruits, vegetables and woody plants. The Horticulture Display Garden provides a venue for education and demonstrates landscape design and plant material options for homeowners and gardeners. Research is conducted in collaboration with the Department of Horticulture Science at the University of Minnesota. The horticulture program utilizes the Horticulture Display Garden, located across Minnesota Highway 329 from the WCROC's main administration building and features several themed gardens and attractions. All plants are labeled, and interpretive signs are located throughout the display garden. The objective of annual flower research at the WCROC is to evaluate various annual and flower varieties for plant height, width, uniformity, flower size, disease resistance and plant quality characteristics. Evaluations are shared with commercial and amateur bedding-plant growers. Each year, the Top Ten Performing Annuals are selected from the hundreds of cultivars trialed. The 2018 Top Ten performers are pictured with variety names throughout this report. West Central Minnesota represents a very distinct climate for annual flower trials. The Morris area typically has hot, dry summers with exposure to wind, which provides a unique opportunity to compare performance of bedding-plant cultivars under regional

conditions. The goal of evaluating flowers is to develop recommendations for our unique climate. Each growing season, hundreds of annual flower cultivars from plant breeding companies around the world are trialed at the WCROC. Cultivars are grown from seed or are vegetatively propagated in our greenhouse. Flowers are evaluated on a variety of characteristics, including plant height, width, uniformity, flower size and disease resistance. Entries in the annual flower trial are evaluated by a certified trial judge throughout the months of June, July and August. Even though the annual flowers are under evaluation, the plants are placed into an aesthetically pleasing design, allowing visitors to enjoy the beauty of the Garden. All flowers are labeled, allowing visitors to take note of top performing cultivars under regional conditions.

The Horticulture Department at the University of Minnesota WCROC would like to thank the many vegetative and seed companies who continue to participate in our Annual Trials. Without their cooperation and support, the research done at the trial gardens would not be possible. In 2018 there were nearly to 400 varieties trialed which included 55 varieties planted in hanging baskets and 77 varieties planted in containers.

Plants were evaluated four times during the growing season; June 22, July 13, July 31 and August 16. This was done to evaluate each variety’s performance. The data was taken by the same individual every time to reduce variability in scoring. Plants were evaluated on their flowering and rated on a scale of 1-5.

Horticultural Rating:

5 = excellent 4 = above average 3 = average 2 = below average 1 = poor

The following traits are considered when giving the ratings: uniformity of habit and flowering, flower numbers relative to others, insect resistance, disease resistance, and uniqueness.

Begonia seedlings received a long day light treatment plus applications of 20-10-20 fertilizer at 75 ppm. Seedlings and vegetative received a drench of plant shield prior to transplant. Plants were transplanted into a soil based mix containing 14-14-14, 3-4 month controlled release fertilizer at a rate of six lbs. per cubic yard. All basket and container media

were planted into soilless media and incorporated with 16-9-12, 5-6 month controlled release fertilizer at a rate of eight lbs. per cubic yard. In addition, an iron chelate supplement was top dressed on Calibrachoa soil media after planting. All bedding plants received supplemental 20-10-20 on a biweekly basis at a rate of 250 ppm early in the season to a rate of 600 ppm late in the season. Containers and hanging baskets were treated with three fungicide applications throughout the season at approximately 30 day intervals.
