'Amethyst' has feathery pink to lilac plumes on top of mounded lacy fern-like foliage. The thick, fluffy panicles are comprised of tiny, densely packed flowers which bloom in late spring to mid summer. The tall, upright stems stand 30 to 36 inches high. 'Amethyst' does best in consistently moist areas with shade to partial shade where it adds a welcome touch of color to a shady garden. It is generally pest free and tough, and is resistant to rabbits and deer. It is attractive to butterflies and hummingbirds. After the blooms have died, the stalks with the dried seed heads are often left in place for winter interest.
