Taxonomy and Nomenclature

• Scientific Name: Cortaderia selloana
• Common Name: Pampas grass
• Genus: Cortaderia
• Family: Poaceae (Grass family)

Distribution and Habitat

• Native to southern South America, particularly the Pampas region.
• Found in moist areas within the South American grassland biome.

Ecological Role

• Considered an invasive species in several regions, including California, Hawaii, and New Zealand. It has been banned in New Zealand and Hawaii.
• Can quickly form massive clumps along roadsides, cliffs, river banks, and disturbed areas.

Morphological Characteristics

• A robust evergreen grass forming large, compact tufts.
• Leaves are narrowly linear and rough-edged.
• Erect stems bear dense silvery or pink-tinged flower panicles.
• Can grow to a height of 6-13 feet (approximately 2-4 meters), sometimes even taller, up to 12 feet.
• Forms large, impressive clumps, 8 to 10 feet high and wide.
• Leaves are folded at the midrib and arise from a tufted base or tussock.

Quirky Facts

• Pampas grass has been associated with swingers in urban myths, although the veracity of this association is questionable.

Interactions with Other Organisms

• Young plants are readily grazed by stock, suggesting a potential role in grazing ecosystems where it's not invasive.
