Silvery new foliage in spring, turning pale grey-green. Makes a good clump to 50cm high if moist and semi-shaded and if very moist it will spread fairly vigorously. Here it has remained a tight clump for years. Pale yellow flowers in September. Very hardy. Introduced by Michael Wickenden some years ago, this went around for a few years as 'Impatiens from China'. For decent soil in shade/semi-shade.
