From Maple Valley Gardens catalog, 1942: BLUE ZENITH (Whiting, R. 1942) M. 40 in. A fine large sky blue iris that will be wanted in every garden. it comes close to campanula blue in the charts, a little deeper than chicory. Did you ever notice how the really blue irises retain their color in late twilight? By this test, Blue Zenith seems to be the bluest one we have; it is like a deep blue sky in June. The flowers are very large, beautifully ruffled and borne on tall, strong. widely branched stems. Its blooming season is lengthened by its excellent substance and the many buds on each stalk; it comes from Blue Hill x Sierra Blue and has the lovely ruffled form, white board and pure coloring of the former with the size and height of the latter and better branching than either of them. The plants are very strong growing and free with both bloom and increase. $15.00.
BLUE ZENITH (Whiting, 1942): Much bluer than most of the medium blues, in fact color is superb. Falls are a trifle too narrow and growth does not seem to be especially vigorous. Mr. Sanford, Pa.; A lovely clear campanula blue, takes the sun well. Calif. [“Varietal Comments” The Bulletin of the American Iris Society, No. 103, (October 1946): 61.
