Dark stems are nearly black on this clumping, easy-to-grow perennial, rising 4’ in summer, topped with fluffy lavender-pink flowers. Clumps of ferny foliage are bright green and lush. Sun (stems are darkest in full sun) to part shade, prefers rich, moist soil (but tolerates average soil). Nice at back of border but filmy enough to be used mid border.
