OXEYE DAISY, WHITE DAISY, WHITE WEED, OR POVERTY WEED, 

 Chrysanthemum leucanthemum (L). 



The Oxeye Daisy is a weed naturalized from Europe, and is very 

 closely related to the Chrysanthemum, or national flower of Japan. 



It is a perennial, with shorb, thick rootstocks, possessed of much 

 vitality. Very many stems spring from one root. It grows from 6 inches- 

 to 3 feet high. The leaves slightly clasp the stem, the lower ones narrow,, 

 long, and toothed along the edges, the upper ones small and without 

 teeth. They are slightly aromatic, more perceptibly so if bruised. The 

 flowers are 1 to 2 inches broad, on long stalks, with from 20 to 30 white 

 rays and bright yellow disc. The seed is about 1-12 in. long and angled, 

 with alternate white and black loiigtitudinal ribs. It has a short point,, 

 but no pappus (Fig. 27). An average plant produces 7,500 seeds. 



Time of flowering, June-August. 



Time of seeding, June-September. 



Dispersal chiefly in grass seed and by birds. 



Eradication. The Daisy is most troublesome in pastures, and cam 

 be got rid of only by breaking up the sod. It can be eradicated by the 

 method outlined for Canada Thistle (Fig. 29).
