CHAPTER IV 

 WHEN TO SOW 



PERENNIALS 



When depending on your own nursery for the first 

 garden supply all but a few of the plants named in 

 this chapter may be started from seeds, the earlier in 

 in the season, the better bloom the next year. The 

 most important plants to keep in stock afterward are: 

 First, those which take longest to mature, and which 

 may die out within five years; and, second, those 

 which grow quickly, but which are more or less short- 

 lived. 



Start Two Years Before Required 



KEEP SOME IN STOCK 



Pyrethrum hybrid.* Salvia pratensis. 



Columbine. Delphinium formosum. 



Salvia azurea, var. Pitcheri. Delphinium hybrid. 



Monkshood Wilsoni. Platycodon. 



Anemone Japonica. Oriental Poppy. 



These are likely to die within five years, excepting Poppy, 

 Platycodon, and Anemone Jap. 



All self-sow quite freely excepting Platycodon, Anemone, 

 and Salvia azurea. 



* The perennials most quickly killed by overcrowding are Pyrethrum 

 hybrid, Lily candidum, and Shasta Daisy. In a dry climate the Lupin 

 is better for some shading from the neighboring plants, but will suffer if 

 deprived of all air, dew, and water, as when the heavy foliage of a near-by 

 plant covers it over completely.
