References:

From Cooley's Garden 1959 catalog: SILVERTONE (Hall, 1959) Each $20.00. A beautifully proportioned silvery pale blue - almost white - with tangerine beard. There is a slight hint of orchid in the color of this very large Iris. As seedling No. 53-32 it was the chief attraction of all visitors and was awarded an H.C. certificate in 1954. Everybody wanted to know when it would be ready for introduction. But it bloomed too heavily to provide a sufficient number of plants until this season and so we are happy to offer it for the first time. It has been used by Mr. Hall to obtain a wide range of seedlings in pale orchid and blue-white tints with tangerine beards. This is a parent of "Step Forward", introduced this year. Heavy stems, 36 inches.
