Cortaderia selloana 'Rendatleri'
ABOUT
Cortaderia selloana 'Rendatleri', commonly known as Pampas Grass, is characterized by its gracefully arching foliage and showy flower plumes. The leaves of this ornamental grass are narrow, long, and have a sharp edge that can easily cut skin if handled without care. Generally colored in a silvery green or blue-green hue, the foliage forms a dense, tussock-like clump from which the flowering stems emerge. In bloom, Pampas Grass produces towering feathery plumes. These plumes are notably fluffy and soft, resembling large feather dusters, with a silvery to creamy-white color that can sometimes have hints of pink or purple. These inflorescences appear in the late summer to fall and can last into the winter, providing interest even in the colder months. The contrast between the delicate, airy plumes and the robust foliage creates a distinctive appearance that stands out in any landscape setting. This plant is often used as a specimen or in groups to create dramatic effects in gardens, especially given its notable flower plumes which can catch the sunlight and move gently with the wind.

WaterPampas Grass should be watered deeply about once a week during its growing season, which is typically in the spring and summer. This grass prefers a thorough watering that allows moisture to penetrate deep into the soil, promoting deep root growth. As a guideline, provide about 1 to 1.5 gallons of water per plant for each watering session. During periods of extreme heat or drought, you may need to water more frequently, while in cooler months or rainy seasons, you can reduce watering. Ensure the soil is allowed to dry out slightly between watering to prevent root rot.
LightPampas Grass thrives in full sun conditions, requiring at least 6 hours of direct sunlight daily to grow well. The ideal spot for planting Pampas Grass is an area where it can receive unfiltered sunlight throughout the day. While it can tolerate some light shade, too much shade can result in a weaker plant with fewer plumes.
TemperaturePampas Grass is hardy and can withstand a temperature range from about 20°F to over 100°F. But the ideal temperature for optimal growth is between 60°F and 80°F. Pampas Grass will remain dormant during colder winter months and may require protection if temperatures drop significantly below 20°F.
PruningPampas Grass should be pruned to remove old foliage and make way for new growth, usually in late winter or early spring before new shoots appear. Pruning involves cutting the grass down to about 1 to 2 feet above ground level. This yearly pruning is also important for maintaining plant health and size. Always wear gloves and long sleeves when pruning Pampas Grass, as the leaves can have sharp edges.
CleaningAs needed
SoilPampas Grass thrives in well-draining soil with a pH between 6.0 and 7.5. A mix of loam, compost, and sand or perlite encourages healthy growth. The recipe should mimic prairie soils, rich in organic matter yet efficient at water drainage.
RepottingPampas Grass being a large perennial, typically does not require frequent repotting. Once established, it's often best left undisturbed due to its size and root structure.
Humidity & MistingPampas Grass tolerates a wide range of humidity levels and thrives in an average outdoor environment without the need for specific humidity adjustments.
Suitable locationsIndoor
Grow Pampas Grass inside with ample light, minimal water.
Outdoor
Plant Pampas Grass in full sun, well-drained soil, space generously.

Life cycleCortaderia selloana 'Rendatleri', commonly known as Pampas Grass, begins its life cycle with seed germination, which requires a well-drained soil and full sun exposure. Seedlings develop into tufted grass clumps, establishing a strong root system which is key for the perennial growth. As the plant matures, it produces long, narrow leaves that can reach several feet in length. In the following years, Pampas Grass enters its flowering stage, typically late in summer through fall, producing tall, feathery plumes that can extend several feet above the foliage. After pollination by wind, seeds are produced which can be dispersed by wind or mechanical means, continuing the life cycle. In colder climates or as the plant ages, it will undergo a period of dormancy in winter, resuming growth as temperatures rise in spring.
PropogationPropogation time
Spring-Early Summer
Propogation: The most popular method of propagation for Cortaderia selloana 'Rendatleri', commonly known as Pampas Grass, is through division. This is typically done in the late winter or early spring before new growth starts. To propagate by division, the gardener should dig up the entire clump of the grass, ensuring to get as much of the root system as possible. The clump is then divided into smaller sections using a sharp spade or knife. Each section should have a portion of the root system and several growing points. The divisions can then be replanted immediately in well-draining soil, watering them in well to help establish the new plants. It's important to space the divisions about 6 feet apart (approximately 1.8 meters) to allow for their future growth.
