I20. Platycodon Mariesi, van album {Continued) 



stems are sufficiently sturdy to stand without support. In order to se- 

 cure a long period of bloom the seeds should not be allowed to form. In 

 fall the dying stems should not be cut to the ground, but should be left 

 to protect the crown. 



Propagate most easily by seed, though the seedHng frequently does 

 not come true to the parent in form and color; or, with more difficulty, by 

 division in early spring. 



Var. flore pleno album. Similar to the type except that the flowers 

 have a double row of petals, one inside the other, forming a ten-pointed 

 star; pretty and interesting, though perhaps not so handsome as the type.
