Montcalm 
This variety is similar in appearance, agronomic characteristics and maturity to Charlevoix, the standard dark red kidney variety in Michigan. Like Charlevoix, it has excellent seed type with good canning and salad quality. Under moderate to heavy halo blight infestations, Montcalm will outyield Charlevoix. In the absence of halo blight, they will have comparable yields. Like Charlevoix, Montcalm is susceptible to common bacterial blight, and consequently a clean seed program has been employed in its increase.
