Red natal grass

Melinis repens

Melinis repens, commonly known as Natal redtop or simply Natal grass, is a warm-season perennial grass that belongs to the Poaceae family. Native to Africa, Natal grass has been introduced to various parts of the world and is known for its aggressive growth and potential to become invasive. Here's an informative description:

Appearance:

  1. Growth Form:

    • Natal grass is a tufted, perennial grass that can form dense clumps.

  2. Leaves:

    • The leaves are linear, long, and slender. They are typically green but can take on a reddish tint, especially at the tips.

  3. Flowering Inflorescence:

    • The flowering structure is a feathery panicle with reddish or purplish spikelets, giving the plant a distinctive appearance.

Identification:

  1. Feathery Panicle:

    • The feathery panicle is a key identifier, especially when it takes on a reddish or purplish color.

  2. Tufted Growth Habit:

    • The tufted growth habit contributes to the formation of dense clumps.

Habitat and Distribution:

  1. Habitat:

    • Natal grass is commonly found in disturbed areas, roadsides, pastures, and along watercourses.

  2. Distribution:

    • Native to Africa, it has been introduced to various regions and can be found in parts of Asia, Australia, and the Americas.

Ecological and Agricultural Impact:

  1. Invasiveness:

    • Natal grass is considered invasive in some regions where it outcompetes native vegetation and disrupts natural ecosystems.

  2. Forage Potential:

    • While it can be invasive, in certain contexts, Natal grass is also used as a forage grass for livestock.

Management:

  1. Herbicides:

    • In cases where Natal grass is considered invasive, selective herbicides may be used to control its growth.

  2. Mechanical Control:

    • Mowing or cutting back the grass can help manage its spread, especially before it produces seeds.

  3. Preventive Measures:

    • Implementing measures to prevent the introduction and spread of Natal grass in new areas is crucial for its control.

  4. Alternative Ground Cover:

    • Establishing desirable native vegetation or alternative ground cover can help suppress the growth of Natal grass.
