64 A TEXT-BOOK OF GRASSES 
Buffalo-grass gives excellent results in the semi-arid 
region of the Great Plains. The seed is not on the market 
but the grass is easily grown from cuttings. It forms a 
firm sod like Bermuda-grass and has the same objection 
of being light green in color. Buffalo-grass requires no 
mowing as the foliage remains short and curly. 
Rye-grass is sometimes used for lawns though it pos- 
sesses few of the necessary characteristics. It is used 
chiefly in mixtures to produce quick results as it grows 
vigorously the first season. It is coarse and bunchy and 
not suited to a lawn when sown alone. 
Korean lawn-grass is coming into use along the coast 
from South Carolina to Florida. 
82. Lawn mixtures.—One of the characteristics of an 
ideal lawn is uniformity of texture. This can be obtained 
only when a lawn is made up of a single species. To pro- 
duce a lawn of uniform texture requires special care. 
From the standpoint of practicability it may not 
always be convenient or even possible to fulfil the con- 
ditions necessary for an ideal lawn. Hence, the use of 
mixtures by which better results in some ways may: be 
obtained than by using a single species. This applies 
particularly to the humid regions. The character or con- 
dition of the soil may be such as to prevent the produc- 
tion of a uniform stand of a single species. It is well 
known that a properly chosen mixture will in these cases 
produce a thicker turf and will do so in a shorter time than 
if a single species is grown. 
The chief or even the only objection to a mixture is 
the lack of uniformity. A closely mown lawn will show 
variations in color corresponding to the different species 
of which it is composed. Rye-grass is sometimes included 
in a mixture to give quick returns, the other components
