From the Cayeux et Le Clerc catalog for 1930, p. 9: "Up to the present time, we have not seen anything yet in the way of this fine and distinct Iris; the delightful colors, the enormous size and the perfect shape of its flowers are unrivalled. Standards pure white. falls wide, almost flat spreaded with a suffusion of soft sky-blue on the center; large throat strongly reticulated fawn; the whole of an exquisitely fresh appearance. As seen on the figure, the firm stems 4 feet high, well branched, bears 4 to 5 flowers expended at the time. Exceedingly free, a grand toned Iris for landscape." |
From Quality Gardens catalog 1931: YVES LASSAILLY (Evee Las-ayee) (Cayeux 1929) E. 48". This is a giant both in stem and flower. It is a very beautiful combination of white and blue. The colors are the same as in Los Angeles, except that in Los Angeles, the background is white, while the standards are faintly edged blue. In Yves Lassailly, the standards are white, and the very broad white falls have a suffusion of soft sky blue in the center. The firm stems, well branched, carry 4 to 5 flowers, open at one time. We strongly recommend this to our customers. $12.50. |
