Native bentgrass in lawns
Native creeping bentgrass is found in several places such as roadsides, fields, meadows, edges of sidewalks and parking entrances. It produces a large number of very small seed that is easily moved by wind or by other means to reach lawns where it will germinate and produces a dense tillering.
With its strong growth of stolons (a stolon is an aerial creeping stem), bentgrass multiplies rapidly to form patches invading Kentucky bluegrass lawn. Native bentgrass has a light green foliage that does not go along with the dark green colour of Kentucky bluegrass.
It is not easy to walk over a lawn of bluegrass invaded by dense patches of native creeping bentgrass. In addition, mowing scalps the elevated patches of native bentgrass that turn temporarily brown.
