The `Adelaide Hoodless` variety was crossed with Rosa arkansana Porter to obtain an offspring that was crossed with the `Mount Shasta` variety. This cross produced a parent used in the creation of the new variety. The other parent of the new variety was formed by the crossing of the `Prairie Princess` variety and the `Morden Amorette` variety. None of the plants used to create the new variety have been patented in the United States. The `Prairie Princess` variety is a shrub rose (Rosa sp.) developed by G. Buck in 1972 and the `Mount Shasta` variety is grandiflora rose (Rosa sp.) developed by Swim and Weeks during 1963.
In September 1998, the Montreal Botanical Garden (Le Jardin Botanique de Montreal) carried out a survey of its roses' resistance to black spot, powdery mildew and rust. This is one of the outstanding varieties which showed a 0% to 5% infection rate. The data were taken on well-established roses.
