Winners from the 2010 Colorado State University Annual Flower Trial Gardens

April 25, 2011

Colorado weather can make for difficult growing conditions, especially for flower lovers. From searing heat to severe weather to lack of moisture, it can be a challenge to produce abundant flowers. In an effort to aid both homeowners and commercial growing operations, Colorado State University has released the results of its 'Best of' 2010 annual flower trials.

More than 1,100 plantings

More than 1,100 different varieties of annuals were either given trial plantings in ground beds or in about 600 containers at the Flower Trial Gardens, 1401 Remington St. in Fort Collins. The garden, west of the University Center for the Arts, is managed by CSU’s Department of Horticulture and Landscape Architecture in cooperation with a committee of local growers, bedding plant personnel and public garden horticulturalists.

One of largest flower test gardens in U.S.

“The Annual Flower Trial Garden gives us the perfect opportunity to evaluate annual flowers to see how well they perform in Colorado’s high light intensity and low humidity," said Jim Klett, professor in the Department of Horticulture and Landscape Architecture at Colorado State. Klett manages CSU’s Flower Trial Gardens, the largest flower test garden in the state and one of the five largest in the United States.  

Twenty-six seed and vegetative companies from within the United States and worldwide participated in the trials. Judging was held on Aug. 9, 2010, and again on Sept. 8, 2010, to determine the 2010 “Best of” winners.

And the winners are...

Denver Daisy, Best of ShowThe Best of Show is Denver Daisy from Benary Seed. The abundant large flowers are very showy with a long bloom time. The flowering and growth habit are exceptionally uniform. Denver Daisy was a past winner in the annual flower trials and also a Grand Prize Winner in public voting through the American Garden Award Program.

The Best New Variety is Graceful Grasses Vertigo from Proven Winners. This plant has impressive vigor. Its large size and dark purplish glossy foliage makes it a unique focal point in the garden.

Best Novelty for 2010 is Yellow Compact from Grolink Plant Company. This bulbine makes a unique impression due to its delicate yellow flowers on the tips of uprights stems. The foliage has a fine grass-like texture.
