WILD ROSE 27 



flowering the early part of June and flowers and seeds until the 

 latter part of September. The plant is somewhat spreading in its 

 character and often grows quite near the ground. The leaves are 

 three-lobed and not five-lobed as the name would indicate. The plant 

 is quite hairy and sometimes grows to a height of three feet. The 

 yellow flowers are about half an inch broad. The plant is propagated 

 chiefly by its seeds, which are very small, light brown in color, and 

 have a wrinkled surface. They are found chiefly in timothy, lawn 

 grass, and many of the other commercial grasses. 



Eradication. — Avoid sowing grass seeds containing seeds of this 

 weed. Destroy the plants by hoeing, cultivating, or cutting before 

 seeds mature. Will yield to clean farming and short rotation schemes 

 in which the grass crops are used for hay and the intertilled crops are 

 thoroughly cultivated. 



Wild Rose (Species of Rosa) 



Other common names. — Sweet briar and eglantine. 



Description. — The wild rose is a perennial weed which grows 

 very commonly along roadsides and also in cultivated fields and 

 waste places. The plant flowers during practically the entire sum- 

 mer, and seeds are mature in the early fall. The fruit of the wild 

 rose varies from orange to bright red and is somewhat berry-like in 

 appearance. The seeds are hard and nutlike. The wild rose is 

 quite variable in height, sometimes reaching a height of three or four 

 feet, while at other times it is very low and bushy. There are two 

 common species of the wild rose growing in this State. The large 

 attractive flowers, which are generally borne singly, although some- 

 times in clusters, range from white to a dark pink or even red. The 

 plant is propagated by seeds and also by running root stalks. The 

 seeds are quite variable in shape and color, the latter being, however, 

 generally a dark brown. They are most commonly found in the seed 

 of wheat, oats, and other cereals. It is sometimes quite difficult to 

 separate the seed from wheat because it is of practically the same size. 



Eradication. — The wild rose is one of the troublesome weeds 

 of the prairie section. Its deep, perennial, underground stems make 

 it very persistent. It is especially troublesome where the grain is 

 "stubbled in" without plowing the land. The best remedy is plowing 

 thoroughly with a sharp plow, cutting the entire furrow slice so that all 

 roots will be cut off clean. If the plowing can be done in August or 

 early in September and the land disked several times at intervals of 

 a week or ten days, the roots will almost surely be destroyed.
