L83 is listed as a Hybrid kordesii, created at the Canadian Experimental Agriculture Farm (aka AgCan) circa 1988. Its parentage is listed as R. kordesii X a 'Max Graf' derivative. This makes it a combination of only two species: R. wichurana and R. rugosa.About as far from being a romantic name as you can get, L83 is potentially a very valuable breeding plant. Although it was not introduced into commerce, it has been exchanged from hybridizer to hybridizer over the years solely for the purpose of breeding new Winter hardy, disease free roses. These qualities it passes on quite readily. It also tends to pass on excellent, glossy foliage and superior vigor. Plants are a mix of climbers and shrubs, and many have very good repeat bloom. Unfortunately it is difficult to get it to breed any colors but pinks, but with perseverance it is possible. (See link to 77-07-23 below)
Noteable hybrids from L83 includes 'AC Marie Victorin, 'George Vancouver', 'Prairie Celebration', 'Rosy Vision', 'Irma', and 'Louis Jolliet'. I also have a number of seedlings currently being grown and evaluated, the most attractive so far being 77-07-23, a brilliant red cluster flowering shrub. Read more about it on HMF
