From Stevens Bros. catalog for 1957-58: “We chose the name Polar Cap as eminently suitable for this iris with its huge domed standards of snowy white, and circular, almost convex falls of stiffly cool, pale lavender-blue. It took many years of breeding to develop this combination, a combination which is entirely new to the iris world. The flowers are large, of massive substance, and have an exceptionally long individual life, retaining their form to the last. When the bloom first opens the colour in the falls is a soft lavender-blue, which lightens gradually to a pastel tone which holds throughout the life of the flower, even in strong sunlight. The standards are a real snowy white, no hint of cream or blue to mar their purity, and form an opulent rigid dome, virgin, cool, and sparkling.”
