Grown for its early blooming feathery flowers, Stipa calamagrostis is a lovely and graceful free-flowering ornamental grass. Deciduous, with an open growth habit, it exhibits arching, blue-green thread-like leaves topped in summer with a haze of silvery white flower plumes, that sway gracefully in the slightest breeze. As they mature, both flowers and foliage turn to a beautiful buff color that persist into winter.
