Clotilde Soupert is said to have been derived from a cross of the blush white Polyantha, Mignonette, and the creamy white, shaded salmon, Tea Rose Mme. Damaizin. The tendency of Clotilde Soupert to produce frequently a red blossom makes such a parentage improbable, as neither Mignonette or Mme. Damaizin had an ancestor of that color. In other respects, the generally accepted parentage is possible, but if the genes for a primary color do not exist in the parents, they are not likely to occur in the progeny, and we must therefore assume that the parentage of Clotilde Soupert is incorrectly recorded.

Polyantha Roses
Polyanthas are, perhaps the most truly everblooming of all Roses, being scarcely ever out of flower during the whole growing season... They are especially valuable for massing, edging, and to some extent for mingling with other flowers.

….but Clotilde Soupert was long since turned out of this Eden because she was too lazy to tend and open her buds properly, and, after much promise, presented dropsical yet constricted blossoms that blighted instead of bloomed.
