While early creeping bentgrasses quickly gave way to annual bluegrass, newer cultivars are much more competitive and may prove to be much more persistent. All of these are high-density grasses tolerant of very low mowing. Every single bent strain in T-1 was tested against Poa annua, so much so that T-1 makes visible gains against Poa annua each year.T-1 sets a new standard for bentgrass tiller density, providing a rich, smooth putting surface. It was developed in Sweden from Congressional bentgrass (C 19).
