CHASKA, Minn. (FOX 9) - Minnesota is home to one of eight Dahlia Trial Gardens in North America, where flowers are judged to see if they're worthy to be sold to people to use in their home gardens.
The Dahlia Society of Minnesota each year plants a new selection of hybrid dahlias in the trial garden at the Minnesota Landscape Arboretum. The flowers are sent in by hybridizers from around the country, and then the Dahlia Society of Minnesota judges the flowers to see if they're worthy of being sold. Judges evaluate seven characteristics: form, color, substance, stem, foliage, bloom position and floriferousness.
Dahlias are a popular flower because they bloom in late summer and fall, with the Arboretum's website noting the trial garden is most beautiful in August and September.
