 ranging in color from pure white through pink to rich crimson-red 

 and also pale yellow, with bright yellow centres in the single forms; pro- 

 fusely borne on the ends 

 of erect, rarely branching 

 stems one totwo feethigh. 

 Leaves very finely divided 

 and rather inconspicuous. 

 Excellent in masses in the 

 herbaceous border on ac- 

 count of the brilliance and 

 profusion of its flowers. 

 Good also for cutting. If 

 the flowers are picked as 

 soon as they begin to fade 

 the period of bloom will be 

 prolonged, or if the plants 

 be cut down after June a 

 good second crop will be 

 borne in the fall.

 easy culture in rich, sandy, 

 well-drained loam. In 

 heavy or badly drained 

 soil the plants are not 

 hardy. Should be planted 

 in full sun, but the roots 

 should be kept cool and 

 moistbyshadeorbetterby 

 a mulch of manure. In 

 planting the ground should be deeply dug and well enriched with manure.
