392 THE NURSERY-MANUAL 



Philodendron. Aracece. 



Propagated by dividing the stems, allowing two or three joints 

 to each piece, struck under glass ; also by seeds when they are 

 obtainable. See Aracece, page 239. 



Phlomis. Labiates. 



Seeds usually grow readily ; cuttings of green wood may also be 

 employed ; division of strong stools. 



Phlox. Polemoniacece. 



The annuals are grown from seeds sown in the open or sometimes 

 started inside. The perennials are grown from seeds, divisions, 

 cuttings of stems and roots. Cuttings made in summer, and handled 

 in a frame, do well. The roots are sometimes cut into short pieces, 

 and are then handled in pans or flats under cover. The showy 

 summer-blooming perennial phloxes (of the P. decussata type) are 

 grown from cuttings of side shoots in summer and also of stronger 

 and more mature shoots. t 



Phoenix. Palmaeece. 



The species grown for ornament are generally increased by 

 suckers and seeds, the seeds usually being imported. See also Date. 



Phormium (New Zealand Flax). Liliacece. 



Seeds sown in February will make good plants for bedding purposes 

 the spring of the following year. Also increased by division of the 

 crowns before growth begins in spring. 



Photinia. Rosaceae. 



Propagated by seeds and by cuttings of half -ripened wood under 

 glass and by layers ; also by grafting on hawthorn or quince. The 

 genus is now usually defined separately from Eriobotrya ; seeLoquat. 



Phragmopedilum (part of the group of greenhouse cypripediums). 

 Orchidacece. 



Propagated by division and seeds. See Orchids, page 372. 

 Phygelius. Scrophulariacece. 



Propagated by seeds; also by cuttings, taken from the late 

 autumn shoots of outdoor plants, or from growths arising from 

 stock plants. 



Phyllanthus. Euphorbiaceoe. 



Propagated by cuttings of ripe shoots taken in August or before, 

 which will root in sand if placed under a glass and in bottom heat.
