From AIS Bulletin #221 April 1976 Introducing ROCKET BLAST (Marsh '76). TB, 32", M. (66-54 yellow sdlg. X Sun Temple). This iris has 32" well-branched stalks carrying up to ten very large flowers. The bright yellow standards are nicely ruffled, arched out and closed at top. The wide-hafted falls are bright yellow with white below the heavy orange beard, and are ruffled and fluted all around. The substance is very good. The stalks are strong and have never needed staking. The blue-green foliage is clean. It is a good grower and increaser, and is fertile both ways. HC '75. $25.00. Marsh Gardens.
