top of the soil and too 

 lightly covered. In the 

 former case the 

 "crown" or heart of 

 the plants wiU rot; 

 whereas, if the plant 

 is not set deep enough, 

 the roots will dry out. 

 The wide diversity 

 in root forms of peren- 

 nials makes it impos- 

 sible to stipulate any 

 specific depth for plant- 

 ing them, but it should 

 be an easy matter to 

 judge the proper depth 

 to plant on seeing the 

 subject. 



All perennials that 

 start into growth and, 

 as a rule, flower in 

 early Spring (such as 

 the Peony), should be 

 planted in the Fall; for 

 those with a late bloom- 

 ing period and a dis- 

 tinct crown of leaves on 

 a more or less fleshy 

 root, such as Foxglove 

 or Poppy, Spring plant- 

 ing is best. With a few such exceptions perennials can be planted 

 either in Spring or in Fall after growth is finished. Fall-planted 

 Peonies are sometimes "blinded" by a too heavy Winter covering — 

 that is, they are prevented from blooming although they grow luxu- 

 riantly otherwise.
