very minute insect which is usually found in the heart of a Rose bloom, 

 they cause a shabby appearance of the petalage. Seed production is a 

 most debihtating process; the plant therefore should be prevented from 

 doing this excessive labor. When the old flowers are picked the 

 energies are often turned to a second crop of bloom. Many dead leaves 

 are diseased and are a menace to the other plants. Besides this, old 

 flowers, dead leaves and seed pods give an air of untidiness to the 

 garden. 



The Propagation of Perennials is discussed in a separate chapter, 

 "Plant Propagation," which see. 



Necessity for Replanting 



Some of the later blooming perennials, especially Helianthus, 

 Rudbeckia, Asters, Boltonia, Physostegia, Achillea, need to be re- 

 planted or parts of them removed each year. Five to eight shoots of 

 these perennials can be left and the rest dug up and moved to another 

 place. This is the only way to keep some of the weedier growers in 

 subjection. Perennials which bloom from crowns in the early Spring 

 are usuaUy impatient of being moved oft«n, examples being Bleeding 

 Heart, Oriental Poppy, Dictamnus, Red Hot Poker and Peony. Iris 

 reproduces rapidly and is best divided every two or three years; Phlox 

 every three or four years and Peony only every three to five years. 

 Many perennials, as Delphinium and Columbine, increase by a gradual 

 enlargement of the crown.
