* propagated by a sort of cutting, made by removing and root- 

 ing the sprouts which appear about the base of the tree. 

 These root readily if taken off green and liberally supplied 

 with water. They often begin to bear in five or six years. 



Date Palm. See Phoenix. 

 Datisca. Datiscece. 



May be increased by seeds, and by dividing well estab- 

 lished plants. 



Datura, including Brugmansia, Ceratocaulis and Stramonium. 



Solanacece. 



The annual species are propagated by seeds, which are 

 started under cover in the north. The perennials are readily 

 grown from cuttings in mild heat. Heeled shoots are usu- 

 ally preferred. 



Daubenya. Liliacecc. 



Increased by offsets. 

 Davallia. Fihces. 



Propagated largely by division. See Ferns. 

 Daviesia. Leguminosce. 



Seed may be sown in slight heat in spring. Cuttings may 

 be made of firm young shoots, and placed in sand under a 

 frame. 



Day Lily. See Hemerocallis. 

 Deciduous Cypress. See Taxodium. 

 Decumaria. Saxifragece. 



Seeds. Cuttings may be made in summer, and placed 

 under a frame in a shady situation. 



Delphinium (Larkspur). Ranunculacece. 



Seeds may be sown out-doors in a warm border in spring, 

 or in pans, to be placed either in frames or outside. The 

 old plants of perennial sorts may be cut down after flower- 

 ing, when young growths will proceed from the base, and the 

 whole may be lifted and carefully divided. Cuttings of the 

 young shoots, taken in autumn or spring, will root freely if 

 potted singly and placed in a cold-frame. They will flower 

 the following season at the same time as the divisions. 



Dendrobium. Orchidece. 



The methods of propagating these plants have already 

 been mentioned. Where a rapid increase of a new or spec-
