Mid season.Magnolia X ((Gudrun x (Lady Morvyth x Rangatiria))). Schreiner’s 1949. HM 1949, AM 1951.
From the Stevens Bros. catalog for 1952-53: “Many years ago we set out to raise an iris with standards of purest white and falls of gold, being moved thereto by our pleasure in this fresh and lovely combination. Little by little as the years went by we have seen these colours developing amongst our seedlings until in November of 1944, there unfolded this flower, which by reason of its snow white standards rising from the primrose falls we have named ‘Pinnacle’. It is not the white and gold of our original ambition – which we have called ‘Summit’ – and is a very different combination. ‘Pinnacle’ is large and beautifully formed and with excellent substance, and the plant has ideal growth habit. fresh, cool, flawless in its purity of colouring and absolutely unique, this iris has won the awards of the American Iris Society of the Honorable Mention in 1949, and then the Award of Merit in 1951, with a record number of the judges’ votes, and has become world famous.” Schreiner’s 1949.
