A Kordesii Explorer series rose, bred by Ogilvie and introduced in 1991. Born in Quebec, Louis Jolliet left the priesthood to become a fur trader. In 1673 he, Father Marquette and five others travelled far enough south on the Mississippi River to determine that it flowed into the Gulf of Mexico and not into the Pacific Ocean. 'Louis Jolliet' originated from a cross between L83, a line derived from R. kordesii, and a hardy seedling derived from R. kordesii, 'Red Dawn', 'Suzanne' and 'Champlain'. Zone 3, will survive down to –35°C. The photograph has been supplied by Morden Research Station, Agriculture & Agri-Food Canada.
