AIS Award of Merit in 1927, Royal Hort. Society Award in 1930. Hybridized by Arthur Bliss and introduced in 1919. 'Cardinal' is a seedling of the famous 'Dominion' iris.

From the 1928 Lee R. Bonnewitz Iris and Peony catalog of Van Wert, Ohio:
CARDINAL (Bliss). This Dominion Seedling has nicely arched standards of a distinctive shade of lavender, overlaid with rose, and its large, rich prune-purple falls carry the distinctive Dominion shape and texture. This Iris is more sought after than any other one in our collection, and we have often thought it to be the most perfect Iris we have ever seen. $25.00
