AMIGO. (Williamson) 1.) Blue-purple bi-color. Light edge around falls is quite distinctive. 2.) Seen several years. A very wonderful outstanding creation. 3.) A heavy, brilliant bicolor, carrying any distance. I have watched this through four successive seasons, have seen it as one, two and three year plants and consider it one of E. B. Williamson's very finest originations. (American Iris Society, 1935, p. 79).

AMIGO. This iris had one of its best years and stretched out to thirty inches for the tallest growth I have ever seen in Columbus (Ohio). (American Iris Society, 1946).
AMIGO. (Williamson). Striking color especially in falls but can't see the enthusiasm for it, flowers small on what I saw now two years in succession, stalk short. (Belsley, 1939, p. 16).
AMIGO. As always attracting the eye at once, with its beautiful pale violet blue standards and velvet falls edged reddish; flaring; excellent points all through. (Lewis, 1939).

AMIGO. (Williamson 1934), another really fine amoena; the standards are pale violet and the falls black purple with a clearly defined border of almost white. The flowers are not quite so large as in Wabash, but the stalk is fairly well branched. 30". (Pilkington, 1939, p. 32).
Wills, J. (1943). "Of course, I would want AMIGO again as a blue bicolor, with its sharp, striking contrast between the pale blue standards and its rich, velvety falls. AMIGO is also small and low growing, but it blooms regularly, and I do not know of any other that has the same pansy-like effect, except one that will not be introduced until this year." (Wills, 1943). Bulletin of the American Iris Society, 89(April 1943), 14.
