29"^ THE NURSERY LIST. 



Petunia. Solanacea:. 



Seeds, either indoors or in the garden. Choice and 

 double varieties are often increased b}' cuttings, which 

 grow readily. 



Phacelia, Eutoca, Whitla\'ia. HydropJiyllacecc. 



The annuals are increased by seeds, and the perennials 

 by seeds and division. 



Phaiua. Orchidacecc. 



Division of the bulbs. See also under Orchids. 



PhalEenopsis. Orchidacca:. 



These are very slow and difficult to propagate. In the 

 majority of the species it can only be done where a lateral 

 offshoot is made from the main stem. Some species, such 

 as P. Liiddcmanniana, and more rarely P. amabilis, P. 

 Sliiartiana and P. Schilleriana, develop plantlets on the 

 old flower scapes. By pegging these down on a basket 

 of moss they may fje established and afterwards sepa- 

 rated. P. Stiiartiaiia and P. dcliciosa have been known 

 to produce plants on the roots. Other instances of root- 

 proliferation are recorded in Saccolabiinn inicraiilhutn 

 and a species of cyrtopodium. See under Orchids. 



Phalaris. GraininecF. 



Propagated by seeds, but the sports or varieties by 

 division. 



Phaseolus (Bean, Kidney, Pole, String, Lima, French Bean, 

 etc.). Lcguinitioscc. 

 The ornamental greenhouse kinds are grown from seeds 

 planted in light soil in a warm propagating house. See 

 Bean. 



Phellodendron (Cork Tree). Rutaccir. 



Increased by seeds, layers, and by root cuttings. 

 Philadelphus (Mock Orange, Syringa). Sax-ifragacca. 



Seeds, layers, suckers, and cuttings. Layers are some- 

 times used. Cuttings of mature wood are generally em- 

 ployed. Some well-marked varieties, like vars. nana and 

 aurea of P. coronarius, are grown from cuttings of soft 

 wood in summer in frames. 



Phillyrea (Jasmine Box, Mock Privet). Olcacca;. 



Seeds. May be propagated by cuttings, layers, or by 

 grafting on the privet.
