SWEET SUDAN Sorghum vulgare 
A new and distinct grass sorghum developed by the Texas Agricultural Experiment Sta- 
tion through crossing Sudan grass and Leoti sorgo and repeatedly back-crossing to the 
Sudan grass parent. Sweet and juicy stalk, non-shattering seed habit, a distinct sienna 
colored seed and disease resistance have been transferred from the sorgo to the new grass 
sorghum through plant breeding. Resembling common Sudan in plant habit, Sweet Sudan 
is a little later in maturity, more vigorous growing and a higher yielder of both forage 
and seed. The plants are sweet and juicy, more resistant to foliage diseases and chinch 
bugs than common Sudan, and remain green and growing later in the summer and fall. 
Bright reddish seed hulls readily distinguish the variety from common Sudan, Johnson 
grass or other sorghum mixtures. Grazing tests have indicated that livestock prefer Sweet 
Sudan to common Sudan, the grazing period of the pasture is extended and the coarse 
stems are eaten readily. 
SWITCH Panicum virgatum 
A perennial, deeprooted, semi-bunch grass, occurring throughout the tall-grass and 
coastal prairies. Since it is ordinarily considered a “tall” grass it is best suited for hay 
either on alluvial soils or uplands and for pasture mixtures in the humid sections. 
TALL FESCUE Festuca elatior 
Similar to Meadow Fescue but is coarser, more drought-resistant, and more tolerant to 
alkali. Will not stand as much moisture as Meadow Fescue; otherwise the growth 
characteristics are similar. 
VINE MESQUITE Panicum obtusum 
A perennial grass that is tufted from a knotted rootstock. Its widely spreading stolons 
with swollen or knotted nodes often grow to eight or ten feet in length. Under favor- 
able conditions forms a fairly dense turf. Occurs through Oklahoma and Texas west of 
the timber belt, to Arizona, southern Colorado and southern Kansas. Best adapted to 
heavy soils of flats, particularly overflow areas, but will grow on sandy soils. Most useful 
for erosion control and pasture, and in some sections is cut for hay.
