and canna by making as many divisions as there are buds, 

 or rattier separate crowns, as shown in Fig. 32. 



Some of the scaly- bulbed lilies can also be divided and 

 yet remain strong for flowering if 

 separated in sections as indicated 

 by the bulb, as shown in Fig. 33. 



As to the time most favorable for 

 division, at the North the spring is 

 the best period for separating hardy 

 perennials, as it is the period of 

 starting growth. But in mild 

 climates the work is usually done 

 in winter or very early spring. 



But we have many kinds of 

 bulbous or tuberous plants that 

 make all their growth early in spring 

 and rest in summer, such as the narcissus, hyacinth, tulip, 

 dicentra, and perennial poppy. In such cases th<? division 

 follows the ripening of the foliage. 



AVith tubers and rootstalks, such as the daL'ia and 

 carma, the season for division is in the dormant period in 

 au cumn, or prior to time of planting in the spring.
