| From Maple Valley Iris Gardens catalog, 1945: BLUE RYHTHM (No. 4332) Most of us concede that there is as yet no true blue iris. Yet with so many breeders working for one there is bound to be improvement. We think Blue Rhythm is a step nearer to real blue, and a really handsome iris. It comes close to cornflower blue, softened by a silvery over-tone. The flowers are large and full with wide standards arched and domed, and seniiflaring falls. The wide hafts one smooth and blue with no pattern, the substance is especially good. The stalks are 38 to 40 inches tall and widely branched, carrying many flowers. The season of bloom carries over from midseason to late. The plants are robust, free blooming and show above normal increase. $25.00.
| From Carl Salbach catalog 1947: BLUE RHYTHM (Whiting 1945). Most ofthe blue iris are either lavender blues or violet blues. Blue Rhythm is a new approach to real corn flower blue. The handsome flowers are large with standards arched and domed, and with semiflaring falls. The wide hafts are blue with no pattern. Heavy substance. 36", well branched flower stalks. Blooms over a long period of time. Free bloomer. $15.00.
| BLUE RHYTHM (Whiting '45). M. (Annabel: Blue Triumph x Aline) x (Blue Zenith). It's performance that counts. Blue Rhythm always gives a perfect display and is the most dependable first year performer we have ever grown. It should prove a splendid parent. Winner of both the President's Cup and Dykes Medal for 1950 ....... $3.00. Tell's Iris Gardens 1951
