Cortaderia selloana, commonly called pampas grass, is native to Brazil, Argentina and Chile. It was planted around the world in Victorian times, and today is considered to be one of the most popular of the ornamental grasses. This is a tough, large grass that forms dense, substantial clumps (tussocks) featuring arching, finely serrated, narrow green leaves that are topped in fall by huge, feathery, silvery white plumes. It was first introduced into the U. S. in 1848, and for many years now has been grown as an ornamental plant in certain southern and western parts of the U.S. It has also been grown commercially for harvest of its large flower plumes for use in dried arrangements. Leaf blades are extremely sharp. The leaves may reach 6-8’ in length. Flower plumes (1-3’ long) may rise to 10-12’ tall on erect stems. Silvery white plumes (sometimes with traces of pink) are more impressive on female plants than on male plants. Winter hardy to USDA Zones 8-10 where it is best grown in dry to medium moisture, well-drained soils in full sun. Tolerates light shade. Tolerates drought once established. Where winter hardy, this is a large ornamental grass for large landscapes. Excellent specimen. Background plant for borders. Screen. Plumes may be cut and dried for use in indoor flower arrangements.
Growing Instructions for Pampas Grass
- The seeds like moist, well-drained soil. Use a sterile seed starter mix, if available. It prevents soil fungi from damaging the seeds and the seedlings. If not available, then make a mixture of half potting soil and half sand, perlite or vermiculite. 2. Put the soil in a pot. 3. Water the soil so that it is moist but not wet. 4. Sow the seeds on the soil and gently press the seeds in. 5. Place the pots in an area with warm temperatures in full sun or part shade. 6. When the seedlings are a few inches tall, they can be transplanted.
