|From Quality Gardens catalog 1931: THAIS (Ta-ees‘) (Cayeux 1926) M. 42". An ideal, large, perfectly formed flow'er on stately, free growing strong stems, carrying four to five flowers open at a time. A self color, of pale lilac pink; a lighter clearer pink than Susan Bliss. Well rounded falls lighted with golden beard. One of the hardiest, most satisfactory iris we know and the best pink for the money. C. of M. S.X.H.F. S3.25.|

|From Robert Wayman's catalog for 1940: "Early. Very sweet fragrance. Huge flowers of perfect form in a most unusual and attractive pink tone. one of the most gorgeous of our pink toned Irises which makes a marvelous garden mass."|
| From Ted Havelka, 2014: While the beautiful flower style of Thaïs is older, more historic, there are several other strengths this plant also shows, growing in the gardens of the Pacific Northwest. The foliage is one of the cleanest, and most spot-resistant, among bearded class irises growing in Vancouver, Washington and Portland, Oregon gardens. When not in bloom, and up until buds emerge from spathes, Thais is hard to tell from forms of I. pallida. The spathes are papery, often before buds emerge.
There is virtually no side branching on the stems. Flowers below the terminal point are usually very close to the primary stem.
Thais' bud count and duration of bloom are consistently excellent for this Portland gardener. Stems often give twelve or more buds, even where there is less than a full day of direct sun. Bloom sequence is good too, with flowers often drying and dropping before younger buds emerge.
Pod and pollen fertility, so far difficult to gauge. Planted two pods hand-pollinated and harvested in 2011, but saw no germination. Have several pods just picked this 2012 season, and again seeds appear full and sound. In seven to eight months' time should see whether any of these germinate. Also plan to plant seeds of which Thais is the pollen parent, and will be noting germination rates with these also.
As of December 2014, Ted of GPIS has four seedlings of Thais planted near Sherwood Oregon on a small open hilltop in loamy soil. Unfortunately I, Ted am unsure of the pollen parent, but most likely this is Thais x self or Thais x TB Alcazar. Thais over past four years has set pods moderately following hand pollination, but only about one in six pods gives any seed which look viable. Most seed are underdeveloped, small and shriveled. Observe that TB Thais appears much closer in leaf color and geometry, stem branching and spathe characteristics of iris pallida than to hybrid tall bearded iris varieties.-- TedHavelka - 2014-12-05.
