I am especially fond of violets with some age and a story, and "Coeur d'Alsace" is one of my first violets.  As sometimes happens, I lost it entirely for a few years, but now it's back, and I couldn't be happier.  It was first listed  in 1916 and, according to Roy Coombs, it was a cross between "Rubra" and "Le Lilas."  There is some controversy about its origins, however.   In 1938 it was reported to be an "old variety" and not a new hybrid, which was seconded by another person, but their descriptions of the violet seem not to be that of "Coeur d'Alsace" but another violet that was misnamed.  "Coeur d'Alsace" is a medium, warm pink with a trace of salmon.  It was bred in France by Armand Millet, and in 1920 it was awarded the French National Horticultural Society's Certificate of Merit.  Zones 4-9.
