pampas grass


The plant commonly known as pampas grass is a striking and elegant ornamental grass that is well-known for its large, fluffy flower plumes. These impressive plumes emerge above the tufted, clump-forming base and are usually silvery white, though they can also be found in soft shades of pink or purple. The flowers provide a feathery, delicate texture that sways gracefully in the breeze. Pampas grass has long, narrow, and arching leaves that form dense tussocks. The foliage is a bright green to bluish-green color and can be quite sharp to the touch, with edges that resemble serrated blades. During the growing season, these leaves create a lush, fountain-like mound that serves as a stunning backdrop for the showy flower spikes. The plant blooms in the late summer and into the fall, and the plumes it produces can be so dense with flowers that they almost resemble a soft, bristly brush. After the blooming period, the plumes will often persist, providing visual interest throughout the winter months. As they age, the flowers may turn from their original color to a tawny hue, which can add a different aesthetic quality to the garden landscape. Pampas grass is a hardy plant that continues to offer a striking visual element even after the growing season, making it a popular choice for creating focal points in gardens, or for adding structure to large open spaces. Its feathery plumes are also commonly used as cut flowers or in dried floral arrangements, thanks to their enduring beauty.

  • water dropWater

    For Pampas grass (Cortaderia selloana), it's essential to maintain a consistent watering schedule during its growing season in the spring and summer. Water it deeply once a week, providing about 1 to 2 gallons per plant depending on soil conditions and climate. Pampas grass prefers a thorough watering that reaches the deep roots rather than frequent shallow waterings. During periods of drought or extreme heat, increase the frequency to twice a week. In the fall and winter, reduce the amount of water as the plant goes dormant, and heavier rainfall typically supplements its needs.

  • sunLight

    Pampas grass thrives in areas that receive full sun for at least six hours a day. The best spot for this plant is an open area without shade from buildings or trees, as ample sunlight is crucial for its growth and the development of its distinctive plumes. If the grass is planted in too much shade, it may not bloom properly and can become sparse.

  • thermometerTemperature

    Pampas grass prefers temperate conditions and can tolerate a wide range of temperatures. It can survive in conditions as low as 20 degrees Fahrenheit and up to around 100 degrees Fahrenheit. The ideal temperature range for Pampas grass to thrive is between 70 and 90 degrees Fahrenheit. However, it can endure slight dips and spikes outside of this range without significant damage.

  • scissorsPruning

    Pampas grass should be pruned to remove old foliage, encourage new growth, and maintain its shape. The best time to prune is in late winter or early spring before the new growth starts. Cut the grass back to about 1 to 2 feet above the ground. Pruning is typically required once a year, but if the plant becomes too large or messy, additional shaping can be done throughout the growing season.

  • bambooSoil

    Pampas Grass requires a well-draining soil mix with a pH range of 6.1 to 7.5 for optimal growth. A mix of garden soil, peat, and coarse sand in equal parts can provide the right structure and nutrients. Regular fertilization will enhance its lush foliage.

  • plantRepotting

    Pampas Grass doesn't typically require frequent repotting due to its size; however, it may be repotted once it outgrows its current location or when division is performed for propagation, which is usually done every 2 to 3 years.

  • circleLife cycle

    Pampas grass (Cortaderia selloana) starts its life as a seed, which when sown, germinates in warm soil with good sunlight exposure. The seedling establishes a deep root system and begins to grow long, narrow leaves in a dense clump. As the plant matures, generally in late summer to early fall, it sends up tall flower plumes that can be several feet high. These plumes are either male or female, as pampas grass is dioecious, with separate male and female plants. After pollination, typically by wind, the female plants produce seeds that are dispersed by wind and animals. Pampas grass is a perennial, so after the growing season, it becomes dormant in the winter, then regrows from its base the following spring, continuing its cycle for several years.

    • Propogation time

      Spring-Early Summer

    • Propogation: Pampas grass, scientifically known as Cortaderia selloana, is typically propagated through division, which is the most popular method. This involves splitting the large, dense clumps that the plant forms into smaller sections. The ideal time for propagating pampas grass by division is in the late winter or early spring, when the plant is not actively growing. To effectively divide pampas grass, a sharp spade or even a saw may be required due to the toughness of the root ball. It's important to replant the divisions promptly and water them thoroughly to ensure they establish in their new location. Each division should have a substantial piece of the root system and several growing points to foster successful regrowth.
