Quaker Lady, introduced in 1909, is one of the most beautiful iris in existance. It's very generous with its flowers and the colors have an almost magical glow about them.
This iris, pictured with Quaker Lady above, doesn't have a fragrance that I can detect but the pink color is beautiful.
Dogrose (not the same as the iris above) is one of the earliest pinks, introduced in 1930. It has the fine scent of its I. pallida ancestor and like Quaker Lady is a very generous bloomer. A mature clump is breathtaking. There is a smoothness about the form and color that really makes this iris stand out in the same way that Quaker Lady and Helen Collingswood do.
I received this beautiful iris in a trade. I don't know what it is but it's lovely. (Update: It's a dead ringer for Cloudcap, a 1947 iris available at Bluebird Haven Iris Gardens for $3 in 2011).
