Cynodon dactylon
Cynodon dactylon, commonly known as Bermuda grass, and also known as Couch grass in Australia & New Zealand is a grass found worldwide. It is native to Europe, Africa, Australia and much of Asia. It has been introduced to the Americas.[2][3] Contrary to its common name, it is not native to Bermuda and is in fact an abundant invasive species there. In Bermuda it has been known as "crab grass" (also a name for Digitaria sanguinalis). Other names are Dhoob, dūrvā grass, ethana grass, dubo, dog grass, dog's tooth grass,[4] Bahama grass, crab grass, devil's grass, couch grass, Indian doab, arugampul, grama, wiregrass and scutch grass.

Description edit
The blades are a grey-green colour and are short, usually 2–15 cm (0.79–5.91 in) long with rough edges.[5] The erect stems can grow 1–30 cm (0.39–11.81 in) tall. The stems are slightly flattened, often tinged purple in colour.
The seed heads are produced in a cluster of two to six spikes together at the top of the stem, each spike 2–5 cm (0.79–1.97 in) long.[5]
It has a deep root system; in drought situations with penetrable soil, the root system can grow to over 2 metres (6.6 ft) deep, though most of the root mass is less than 60 centimetres (24 in) under the surface. The grass creeps along the ground with its stolons, and roots wherever a node touches the ground, forming a dense mat. C. dactylon reproduces through seeds, stolons, and rhizomes. Growth begins at temperatures above 15 °C (59 °F) with optimum growth between 24 and 37 °C (75 and 99 °F); in winter, the grass becomes dormant and turns brown. Growth is promoted by full sun and retarded by full shade, e.g., close to tree trunks.[citation needed]
Cultivation edit
Cynodon dactylon is widely cultivated in warm climates all over the world between about 30° S and 30° N latitude, and that get between 625 and 1,750 mm (24.6 and 68.9 in) of rainfall a year (or less, if irrigation is available). For example, it is grown in the U.S. mostly in the southern half of the country.
Cultivars edit
Hundreds of cultivars have been created specifically for environmental tolerance and stakeholder requirements. New cultivars are released yearly.[7][8]
Uses edit
Religious edit
Commonly known as "durva" or dūrvāyugma in India, this grass is used in the Ayurveda system of medicine.[9] Performing Puranokta Rudrabhisheka while offering durva 11 times bestows long life. In Hinduism, it is considered important in the worship of Lord Ganesha. A clump of 21 shoots of this grass is usually offered during puja (worship). It has been a part of Hindu rituals since Vedic times. A unique festival called Durga Ashtami, dedicated to this grass, is celebrated on the 8th day of Shukla Paksha of Bhadra month of the Hindu calendar.[10]
It is known as "Arugampul" in Tamil and "Karuka" in Malayalam and is part of the Dashapushpam (Ten sacred flowers) in Kerala.[11]
In Nepal, the grass is known as "dubo" and is used by the Hindus. According to Nepalese Hindus, the grass symbolises long life. The grass is an essential item for the Naga Panchami festival as well as the Gaura festival.[12][13][14] In a Nepalese Hindu wedding, a garland made of this grass is worn by both bride and groom.[15]
This grass is a Yoruba herb used for Esu or Elegba in the Ifá system of orishas.[citation needed]
Medicinal value edit
The rhizomes are reported to act as a diuretic in humans and the grass juice can act as an astringent.[9]
It has been observed that Cynodon dactylon may be selectively eaten by dogs to swiftly induce vomiting when they have gastrointestinal problems. The effect may be due to irritation caused by bristles on the leaf margin.[9]
Other edit
It is fast-growing and tough, making it popular and useful for sports fields, as when damaged it will recover quickly. It is a highly desirable turf grass in warm temperate climates, particularly for those regions where its tolerance to heat and drought enable it to survive where few other grasses do. This combination makes it a frequent choice for golf courses in the southern, southeastern U.S and South Africa. It has a relatively coarse-bladed form with numerous cultivars selected for different turf requirements.
Bermuda grass has been cultivated in saline soils in California's Central Valley, which are too salt-damaged to support agricultural crops; it was successfully irrigated with saline water and used to graze cattle.[16][17]

Ecology edit
Invasive species edit
It is a highly aggressive invasive species, crowding out most other grasses and invading other habitats, and has become a hard-to-eradicate weed in some areas (it can be controlled somewhat with Triclopyr, Mesotrione, Fluazifop-P-butyl, and Glyphosate).[18][19] This weedy nature leads some gardeners to give it the name of "devil grass". Bermuda grass is incredibly difficult to control in flower beds and most herbicides do not work. However, Ornamec, Ornamec 170, Turflon ester (tricyclopyr), and Imazapyr have shown some effectiveness. All of these items are difficult to find in retail stores, as they are primarily marketed to professional landscapers.[20]
The hybrid variety Tifton 85, like some other grasses (e.g. sorghum), produces cyanide under certain conditions,[21] and has been implicated in several livestock deaths.
