Increased by seeds, which should be sown as soon as ripe or else stratified; also by division of old plants.
Nemophila. Hydrophyllaceæ.
Seeds may be sown in late summer or any time during early spring.
Nepenthes (Pitcher Plant). Nepenthaceæ.
Propagated by seeds and cuttings. The seeds must have good drainage, uniform conditions and strong heat (80° to 85°). Sow upon a soil made of peat and fine sphagnum, and keep in a moist and close frame. Cuttings are usually struck in moss in a frame having strong bottom 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. The pot is broken when the plant is removed. When potting off, use very coarse material.
Nepeta, Glechoma (Catmint, Catnip). Labiatæ.
Propagated by sowing seed in spring, or by divisions.
Nephelium, Dimocarpus, Euphoria (Litchi). Sapindaceæ.
May be increased by seeds, or by cuttings made of half-ripened wood.
