On Aug. 8, 2023, over 250 Industry and Master Gardeners gathered at the Colorado State University (CSU) Annual Trial Gardens to judge close to 1200 entries. Results were totaled Sept. 8, 2023, by members of the CSU Annual Trial Garden Advisory Committee to make the final selection of the ‘Best Of’s’ for the 2023 season based on the top favorites results from the August evaluation date. Forty-two categories were judged. Listed below are 15 of the more popular varieties including the Best of Show, Best New Variety and the Best Novelty.
Best Of Show – Dahlia Dahlegria™ Apricot Tricolor from Syngenta
This Dahlia got top honors from both industry and consumer groups due to its unique flower color against the dark foliage. The single petals along with a center eye, and yellow to raspberry to magenta single flower petals, were outstanding. It was also popular with pollinators.
Best New Variety – Begonia Stonehedge Rose Bronze Leaf from Benary
This variety grows tall in height with good stem color and large rose-colored flowers. Leaves also have a nice shine to them. The plant excelled in a sunny location.
Best Novelty – Centaurea FanciFillers Chrome Fountain from Westhoff
