Perennial Ryegrass for overseeding in Winter
Key Points
- Fast germination
- Winter active with Mediterranean genetics
- Wear resistance and recovery
- Attractive glossy mid-green colour
Characteristics and areas of use
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).
Breeding history
Colosseum was bred from the few surviving plants out of a test cricket pitch. The surviving plants were crossed and resulted in a cultivar capable of withstanding extreme adverse conditions. Colosseum has a high endophyte level which helps it to resist insect attack. The inclusion of American genetics also gives the cultivar excellent summer performance. Sowing rate and maintenance Colosseum turf ryegrass can be sown in lawns at 3-5Kg/100m2 (300-500kg/ha). Use the higher seeding rate for faster establishment. In new sports fields and winter over-seeded couchgrass it should be sown at 4-5Kg/100m2 (400-500kg/ha).
Suitable For: Shady Areas
