2.4 Colonial bentgrass (
Agrotis capillaris
)
(Alderson, 1995)
Description: This grass is an introduction from Europe and widely domesticated in U.S. It is a winter-season,
stolon bearing grass, 15 to 40cm tall. This is arranged with dense-tuft, short stolons and dense sod. Leaves are
short, fine-textured, green to dark, basal and light to blue green in colour. Inflorescence is an open panicle,
pyramid or cone-shaped, with abundant short stolons but without rhizomes.
Common varieties: ‘Highland’, ‘Allister’, “Glory’, ‘Tiger II’, ‘Bardot’, ‘Greentime’, ‘SR 7100’,’Tiger’
Low density turf varieties: ‘SR 1700’, ‘SR 7150’, ‘Bardot’
Varieties with fine texture leaves: ‘SR7150’, ‘SR 7100’, ‘Allister’, ‘Tiger-II’
Varieties with coarse texture leaves: ‘Glory’, ‘Bardot’
Importance and uses: It is useful in lawns, golf course fairways, landscaping, and erosion control. It is ideal for
combination with other turf grasses and clovers for grasslands or landscaping around industrial areas. It is tolerant
to moderate winter flooding, high water tables, or poor drainage.
2.5 Creeping Bent grass (
Agrotis stolonifera
)
(Beard, 1973; Pennucci and Langille, 2005)
Description: It is native to Eurasia and North America. The grass is a very fine-textured and bright green in colour.
The leaves are narrow, and rolled in the a bud, auricleless and a long, tapered ligulate. Creeping bentgrass is a
low-growing grass having a shallow root system. It spreads by stolons through formation of a mat or thatch layer
above the soil line. The grass is not tufted and th

Creeping
bentgrass is an allotetraploid with chromosome number 2n = 28. It is cross pollinated and can develop
interspecific hybrids (Dickinson, 1930; Warnke, 2003).

Importance and uses: This is a cool-season grass mainly used in golf course putting greens, lawn bowling greens,
and lawn tennis facilities. It is well adapted to cool and humid regions and grow well in sunny areas but tolerant of
some shade. It is tolerant of low temperatures but will discolour early in the winter.
2.6 Fine fescues
Fescues are popular for their drought as well as their shade tolerance, which makes them a desirable species of
grass because of its suitability to different climatic conditions. Fescue grasses have the capacity to stay green
round the year, which only adds to their desirability as a turfgrass species. Hard fescue, Chewings fescue, (blue)
sheep fescue, creeping red fescue and slender creeping red fescue are the common five species or subspecies.
