You won't find Bermuda grass (Cynodon dactylon) growing in UK lawns but you will certainly spot it in the Mediterranean, Africa and parts of the United States. Also called wire grass, this hardy, fast-growing grass is characterised by short, grey-green blades and purple, spiky flowers.
Bermuda grass has flattened, hairy leaves and flowers that appear as purple spikes 2.5 to 7.5 cm (1 to 3 inches) long. The seeds are lance-shaped and about 1.5 mm (0.05 inches) long.
A fast grower, Bermuda grass can cover a lawn in less than a year, often in as little as 60 days.
Deep, thick mats of roots, which can reach nearly 1.5 metres (5 feet) below the surface, protect Bermuda grass from drought.
Bermuda grass hibernates in cold weather, causing it to turn brown. As a result, it does best in warm climates.
Weed or grass?
Because it is fast-growing and produces a deep roots, Bermuda grass can be an invasive weed in areas where it is unwanted. These same characteristics make it a hardy, drought-resistant grass for lawns and golf courses.
