FARM WEEDS OF CANADA 



NARROW-LEAVED GOLDENROD (Solidago graminifolia 

 (L.) Salisb.). 



Other English names : 

 Yellow Weed. 



Bushy or Fragrant Goldenrod, 



Other Latin names: Euthamia graminifolia (L.) Nutt., 

 Chrysocoma graminifolia L., Solidago lanceolata L. 



Native. Perennial by running rootstocks. Stems erect, 

 branching above into cymes, 2 to 3 feet high, almost smooth. 

 Leaves numerous, linear-lance-shaped, 1 to 5 inches long, the 

 edges rough-hairy. Separate heads of flowers about 1/4 inch 

 across, bright golden-yellow, in dense, flat-topped clusters. 



The seed (Plate 75, fig. 75) is small, white, about 1/12 of 

 an inch long, ovate-oblong, nearly cylindrical, slightly tapering, 

 many ribbed, downy. The pappus is white, consisting of a 

 single row of rough bristles, about twice the length of the seed. 



Time of flowering: July to September; seeds ripe in Sep- 

 tember. 



Propagation: By seeds blown by the wind and by long 

 running rootstocks forming new plants at the tips, which, if 

 left undisturbed, soon form large patches. 



Occurrence : In low land throughout the Dominion. 



Injury: This and many other species of the goldenrods 

 are objectionable in meadows on damp soils, as marsh lands 

 and river bottoms, that are not well suited for general cultivation 

 and rotation of crops. These weeds are unpalatable to stock 

 and their presence in hay entails much waste. 



Remedy: To prevent them from spreading, occasional weeds 

 in the meadow may be destroyed by the application of a handful 

 of salt after cutting. Badly infested land that is wet until late 

 in the spring should be shallow-plowed and thoroughly cultivated 

 as soon as the hay crop is removed. These perennial pests can
