| ALTA CALIFORNIA (Mohr-Mitchell). The aristocrat of yellow iris, holding its large beautiful golden yellow flowers four feet above the ground. The stems are superbly branched, the standards clear yellow, the Falls deep yellow, faintly bronzed, with brown markings on the haft. So firm is the texture that neither the sun nor the rain mar the shapely blossoms. As it contains only 1/8 mesopotamica it should be perfectly hardy. Everyone who has seen this lovely yellow agrees that this is the greatest advance in this color to date, and we venture to predict that it will be used as much in the breeding for future yellows as was Dominion for the dark flowers. 48". $35.00. (Salbach, 1931).

| ALTA CALIFORNIA (Mitchell). First of the big, tall yellows, Alta California is still one of the best. Tallest of all the yellows, and a variety which has been recognized as outstanding wherever grown. Striking for mass planting, and excellent in every way. Color bright bronzy yellow, form of. bloom perfect, and branching habit ideal. H.M., A.I.S. Mid-season. 48" __ 25c; 3 for 50c. (Salbach, 1940).
| So tall and superbly branched an iris as Alta California, first of the series of yellows for which Prof. Mitchell gained such fame, still has great value in landscaping; its substance and sparkling color are still good. (McCombs, 1948, p. 54).
| Alta California: (Mitchell) 1.) One of the best yellows to date for garden value. 2.) The shape of the flower is not perfect and the veining at the haft is a mild defect, but it is a very effective yellow and a great addition to any garden. 3.) The brown veining sometimes noticeable in the haft is almost entirely absent in this locality. (A.I.S., 1935, p. 79).
