. A manual of weeds : with descriptions of all the most pernicious and troublesome plants in the United States and Canada, their habits of growth and distribution, with methods of control . Weeds. 494 OOMPOSITAE {COMPOSITE FAMILY). Fig. 343. —White or Ox-eye Daisy (Chrysan- themum Leucanthemum var. jrinnatifidum). X . These will ripen sufficiently to germinate in ten days after the opening of the flowers. (Fig. 343.) Means of control Sow clean seed. Cleanse the Daisy-cursed meadow with a short rotation of other crops. Though perennial, the roots are shallow and are turned out and killed by the plow. Mow infested meadows as soon as the first flowers appear, in order that the seeds may not have time to ripen. Fre- quently cut and salt the plants of the pasture, which will induce the stock to feed on the leaf-tufts and aid in their de- struction. Roadside and waste-land plants should be cut before seed development, or should even be hoed out, for the benefit of adjacent ground. COSTMARY Chrysdnthemum Balsdmita, L. Var. tanacetoides, Boiss. Other English names: Aleoost, Balsam Herb, Mint Geranium. Introduced. Perennial. Propagates by seeds. Time of bloom: June to September. Seed-time: July to October. Range: Nova Scotia and New England, westward to Ontario and Ohio. Habitat: Roadsides, farmyards, waste places. An escape from gardens;, in some localities it is mistakenly called Lavender, but that is a very different plant. The fragrant leaves were formerly used for flavoring home-brewed ale or beer, but in these days they are occasionally eaten by milch cows and spoil the flavor of milk and butter. Stems one to three feet tall, much branched, finely hairy. Leaves.
