Stipa (Stipa arundinacea Pheasant Tails) - Ornamental grasses add great texture and interest in the mixed border, and this Pheasant's Tail grass is no exception. Grown from Stipa seeds, this clumping evergreen has narrow blades that arch gracefully and are streaked with coppery orange. In midsummer, pendent flowers open that are purplish green and give a misty appearance. Also called New Zealand Wind Grass, this ornamental grass is popular for its delightful form and colors. How To Grow Ornamental Grass Seeds: Many gardeners grow Stipa seeds in a cold frame for protection and hardiness. Start Pheasant's Tail grass seeds in the late winter or early spring. Sow the ornamental grass seeds in quality, well-draining seed starting mix and press the seeds into the soil. Keep the Stipa seeds moist until germination occurs. Once seedlings are large enough to handle, move into a pot and allow to grow on. Transplanting can be done in spring or summer after all frost danger has passed. Ornamental grass care includes trimming the plant back in late winter or early spring before new growth appears. Fertilize each spring. Propagation from division can be done in the spring as well.
