Cortaderia selloana is a species of flowering plant in the Poaceae family. [1] It is referred to by the common name pampas grass, [2] and is native to southern South America, including the Pampas region after which it is named. It is widely distributed throughout the world as a cultivated ornamental and an invasive species.

Etymology

Cortaderia is derived from the Argentine Spanish name 'cortadera', meaning 'cutter', in reference to its razor  sharp leaf margins. [3]

Selloana is named for Friedrich Sellow (1789–1831), a German botanist [3] and naturalist[ citation needed ] from Potsdam who worked as a plant collector in Brazil. [3] He studied the flora of South America, especially that of Brazil. The specific epithet selloana was given by Josef August and Julius Hermann Schultes in 1827.[ citation needed ]

Ecology

The native range of C. selloana includes Argentina, Bolivia, Brazil, Chile, Paraguay, and Uruguay. This region is dominated by tropical forests and grasslands, but C. selloana is typically restricted to moist soil within riparian areas. It is found at lower elevations and at moister sites than the closely related C. jubata. It requires areas with plentiful light and soil moisture. It is capable of long-distance dispersal and uses this ability to colonize disturbed areas such as riverbanks. [4] [5]

Invasive species

Cortaderia has become invasive in mild-winter areas of North America, especially the southern United States. It has also been banned in Hawaii and New Zealand because of its ability to outgrow and displace native plants. In Europe, it was first introduced in the United Kingdom, later spreading to other countries in the continent like Ireland, Portugal, Spain, France, and Italy.[ citation needed ] It is a common urban invader. [6]

Pampas grass is fast-growing and can form large masses along the roads, cliffs, riverbanks, and open areas that have been disturbed by human activities or natural disturbances. Pampas grass can displace native plants and destroy their habitats, reducing biodiversity.[ citation needed ]

The plant also competes with other native plants by monopolizing resources like shade, sunlight, and ground nutrients. Because of the large surface area, the leaves pose a significant fire hazard if placed near flammable substances. [7]

C. selloana often spreads from landscaping plantings. [8] Okada et al., 2007 find this is the source of the California population. [8]

Control

Pampas grass can be controlled through herbicide treatment. To accomplish this, the grass is cut down near the base. Next, a 2% glyphosate chemical solution is combined with a silicone-based surfactant and applied to enhance the penetration potential. This method works best in the fall because there is overall better control compared to other seasons. Another control method is to cut and bag inflorescences to prevent seeds from spreading or pulling seedlings. [9]

Soil disturbance that creates bare ground can promote invasion, so it is essential to minimize disturbance or provide competition to seedlings. In order to control disturbance, applying mulch to exposed bare ground to smother seeds and prevent germination can be done. Also, planting or seeding desirable, non-invasive plants can provide competition to reduce germination and seedling establishment. [9]

C. selloana is considered a promising target for bioherbicide development. [10]

Several cultivars are available, of which the following have gained the Royal Horticultural Society's Award of Garden Merit:

Population biology

Okada et al., 2007 find C. selloana populations are best distinguished by a Bayesian analysis of genetic features such as microsatellites. [8] Algorithms such as STRUCTURE are suitable for this. [8]

In culture

Author Li Hengrui (李恒瑞), whose work Kite Capriccio (風箏暢想曲) describes life as a child in 1950s Fengtai County, Anhui mentions the use of the long stem of the Puwei ( 蒲葦 , Chinese for Cortaderia selloana) in the construction of kites. [18]

Several media outlets reported in the 2010s that it was planted by some couples who practise swinging in the United Kingdom as a way to indicate to other swingers that they enjoy that lifestyle. [19] [20] The reports caused a plunge in already declining sales, but the odd association has been dismissed by enthusiasts of the plant and gardening experts as "silly". [21] [22]

Diseases

O'Donnell et al., 2004 first isolated Fusarium cortaderiae from this species. [23] F. cortaderiae is the cause of Fusarium head blight (FHB) of C. selloana. [23]

Berberis, commonly known as barberry, is a large genus of deciduous and evergreen shrubs from 1–5 m (3.3–16.4 ft) tall, found throughout temperate and subtropical regions of the world. Species diversity is greatest in South America and Asia; Europe, Africa and North America have native species as well. The best-known Berberis species is the European barberry, Berberis vulgaris, which is common in Europe, North Africa, the Middle East, and central Asia, and has been widely introduced in North America.

Ornamental grasses are grasses grown as ornamental plants. Ornamental grasses are popular in many colder hardiness zones for their resilience to cold temperatures and aesthetic value throughout fall and winter seasons.

<i>Hosta</i> Genus of flowering plants in the family Asparagaceae

Hosta is a genus of plants commonly known as hostas, plantain lilies and occasionally by the Japanese name gibōshi. Hostas are widely cultivated as shade-tolerant foliage plants. The genus is currently placed in the family Asparagaceae, subfamily Agavoideae, and is native to northeast Asia. Like many "lilioid monocots", the genus was once classified in the Liliaceae. The genus was named by Austrian botanist Leopold Trattinnick in 1812, in honor of the Austrian botanist Nicholas Thomas Host. In 1817, the generic name Funkia was used by German botanist Kurt Sprengel in honor of Heinrich Christian Funck, a collector of ferns and alpines; this was later used as a common name and can be found in some older literature.

A rampant, clinging evergreen vine, it is a familiar sight in gardens, waste spaces, and wild areas, where it grows on walls, fences, tree trunks, etc. across its native and introduced habitats. As a result of its hardy nature, and its tendency to grow readily without human assistance, ivy attained popularity as an ornamental plant, but escaped plants have become naturalised outside its native range and grow unchecked in myriad wild and cultivated areas. Ivy has considerable cultural significance and symbolism.
