In "Progress in Breeding Hardy Roses," Isabella Preston says,

Chippewa . . . shows the influence of the seed parent in the color of the stems and leaves. The semi-double rose pink flowers are borne in large clusters and last well for this type of rose. The plant showed signs of blackspot this fall. [probably fall 1945]

In "Central Canadian Rose-Breeding," Isabella Preston says this about Chippewa:

R. rubrifolia X White Tausendschön gave one seedling which has been named Chippewa (R.23.04.01). It has reddish foliage similar to the female parent, but the flowers have some extra petals and are paler pink. The height is about seven feet. It sets few seeds; efforts to cross-pollinate it have failed.
