Both the American Iris Society (1951) and the Royal Horticultural Society (1959) granted Stevens an award of merit for its creation. It has been suggested that the originality of 'Pinnacle' would have won Jean the AIS's highest award, the Dykes Medal, if she had been eligible for it. Jean went on to create amoenas in a range of other colours, including deeper yellow, pale blue, plum, and pink shades.
