In 1967, her amoena 'Sunset Snows' with its cocoa-tinged pink falls took third place at an international iris competition in Florence and won cups for the best early variety and for the most original colour, marking the first time a prize in the competition had gone to the southern hemisphere and the first time that a single cultivar had collected three different prizes. Of all of Stevens' introductions, 'Sunset Snows' has been the most used by other hybridisers especially those searching for pink amoenas.
