    A persistent and vigorous growing perennial, once established it can persist for a number of years due to its robust root system. Signal grass will remain green long into the dry season. 
    It is widely adapted to tropical and sub-tropical areas and grows best at temperatuures of 30⁰ - 35⁰ with 1,500mm of annual rainfall.

    Seeds are small and elongated – well filled seeds, with bare seeds averaged at 220,000seeds/kg.

    Seed dormancy can be a problem and can affect establishment.
