Just checked the current temp in Glen Ellyn, Illinois and the mercury is revealing a -6 degree Fahrenheit temperature. It may drop 2 additional degrees at the most. We needn't worry as the hybrid varietals from the Univ of Ninnesota research station are planted in the soil here, those being: Frontenac and La Crescent.
This is only a quick update. The 16-inch layer of snowpack will take care of the rest.
- out!!!!!!!
