Colosseum is a medium-fine, mid-green, perennial ryegrass that is a cross between Mediterranean and American genetics. The Mediterranean genetics gives the turf active winter growth in cooler weather and rapid germination, especially in cold temperatures down to 5°C. It also provides naturally vigorous growth year round and delayed onset of browning in summer.
Colosseum is ideally suited to winter sports grounds, golf tees, golf fairways and lawns receiving heavy wear, especially in the winter. Its attractive glossy mid-green colour coupled with active year round growth makes it visually appealing (its mid-green colour helps to mask the invasion of Poa annua and other grassy weeds).
