366 THE NURSERY-MANUAL 



Nemophila. Hydrophyllacece. 

 Annuals grown from seeds. 



Nepenthes (Pitcher-Plant). Nepenthaceoe. 



Grown from seeds and cuttings. The seeds must have good 

 drainage, uniform conditions and strong heat (80 to 85). Sow 

 on a soil of peat and fine sphagnum, and keep in a moist close frame. 

 Cuttings are usually struck in moss in a frame having strong bot- 

 tom heat. A good plan is to fill a small pot with moss, invert it, 

 and insert the cutting through the hole in the bottom. The pot 

 then keeps the moss uniform in temperature and moisture. The pot 

 is broken when the plant is removed. When potting off, use very 

 coarse material. Cuttings in a close frame in sharp clean sand, 

 kept thoroughly moist and given two months or more to root, will 

 give new cuttings. 



Nepeta. Labiates. 



Grown readily from seeds, the perennials also by division. 



Nephelium : Litchi. 



Nephrolepis. Polypodiaceos. 



Propagated by runners. See Ferns, page 312. 



Nerine (Guernsey Lily). Amaryllidacece. 



Commonly increased by means of bulbels that form about the 

 mother bulbs ; also by seeds when obtainable. 



Nerium (Oleander). Apocynacece. 



Propagated by layers, but mostly grown from cuttings of strong 

 firm shoots, in a close frame, or rooted in bottles of water and after- 

 wards potted in soil. 



Nertera (Bead-Plant). Rubiacece. 



Grown from seeds and by division ; and cuttings usually strike 

 readily. 



Nicandra. Solanacece. 



Grown from seeds, sown in the open border, or under glass in 

 the North. 



Nicotiana. Solanacece. 



Propagated by seeds, started under glass or in a carefully pre- 

 pared seed-bed; the ornamental species sometimes by cuttings.
