petals exhibit a margin and apex that is a very dark fuchsia red This suffuses to a lighter fuchsia pink toward the upper centre, then pink tinted white on the lower centre, throat and base. Basal petals are very broad with blunt apexes. Apial petals are narrower with pointed tips. The tube is white and the receptacle is slightly ridged. Creamy pollen coated anthers sit just below a magenta pink stigma on a magenta red style. The brilliant fuchsia pink buds are acutely pointed.
phylloclades are light green with a broad width. 2-3 short, thick, forward facing dentitions are along each margin to the apex. Some phylloclades carry an extra rudimentary detention on their apex. 'Thor Sarah' was to be a replacement to 'Thor Hiro'. It was test-marketed in Canada and the USA, but proved to be a sensitive grower. It was never patented. 'Thor Sarah' can still be found among many collections.
