From R. Wallace Co. catalog, 1922: Mrs. Alan Gray (Foster, 1909). (Cengialti x Queen of May). One of the most beautiful. The flowers have that neatness and self-colouring noticeable in all the Cengialti seedlings, and are of a delightful lilac shade derived from Queen of May, which gives one the impression of pink in comparing it with other Irises. It is unique in generally bearing a second crop of flowers in August, and no Iris is lovelier when massed in quantity, 2-2½ft. C IX. 1/- each.
