Rodgersia are large, imposing plants with divided finger-like leaves and tall stems that bear star-shaped petalless, white or pink flowers in large, fluffy, pyramidal panicles. The leaves turn yellow to bronze in autumn. Rodgersia is a perennial that grows 4 to 6 feet tall.
Grow Rodgersia in a moist border, a bog garden, or near water. Rodgersia can be naturalized at woodland margins or along shaded streams. Rodgersia prefers partial shade; it can grow in full sun in cool summer regions.
Rodgersia is a genus of six species of vigorous, clump-forming rhizomatous perennials. Rodgersia is native to moist woodland and scrub and streamsides in the mountains of Myanmar, China, Korea, and Japan.
