Best grown in moist, fertile, well-drained soils in part shade. Tolerates full sun in the northern part of its growing range. However, plants often struggle in the hot and humid summers of the deep South where they appreciate afternoon shade or sun dappled shade. If grown in full sun, consistent moisture is important. Plants spread over time by short creeping rhizomes.
Native to rocky slopes and ravines in China, Manchuria and Korea, Mukdenia rossii is a compact herbaceous perennial that grows in a heuchera-like clump to 12” tall. Palmate, rounded, 5-9 lobed, dentate, medium green leaves (to 5” long) acquire attractive bronze tinges by summer. ‘Karasuba’ is a cultivar that features more pronounced crimson red color in the leaf tips throughout summer. It may also be sold under the translated trade name of CRIMSON FANS. White, bell-shaped flowers in branched panicles rise on naked stems above the foliage clump to 16” tall in early spring (April). Mukdenia rossii is synonymous with and formerly known as Aceriphyllum rossii.
