From AIS Bulletin #261 April 1986 Introducing GLACIER KING (Dudley Carson, 1986). TB, EM & RE, 34". Lovely glacial blue that brings a modern flower combined with the rock-hardiness of the iris introductions of the late G. Percy Brown. Quite fertile either way. Spicy fragrance. Fall Blue Contrast X Cloud Baron. $20.00. Avonbank Iris Gardens.
