Vaccinium (Swamp Huckleberry. Whortleberry. Blueberry. Cran- 

 berry) . Ericaceoe. 



Propagated by seeds, layers, root-cuttings, and divisions of the 

 old plants. Some species by hardwood cuttings, for which see 

 cranberry. Huckleberry seeds are small and somewhat difficult 

 to grow. The seeds should be washed from the fruits and stored in 

 sand in a cool place until late in winter. They are then sown in pans 

 or flats on the surface of a soil made of equal parts sand and loam. 

 Cover with fine sphagnum and keep in a cool house or frame, always 

 keeping the seeds moist. Seeds treated in this way may be expected 

 to germinate in a month or two, although they may lie dormant a 

 year. Transplant frequently and keep shaded until large enough 

 to shift for themselves. Layers should be tongued. Cuttings, 2 or 

 3 inches long, of the best roots, made in fall and placed in mild 

 bottom heat in early spring, often give fair satisfaction. Native 

 plants can be obtained from the woods and fields which will give 

 good satisfaction if small specimens are taken. Gaylussacias are 

 handled in the same way as vacciniums. For the most recent 

 methods of handling this class of plants, see Blueberry. 



Valeriana (Valerian). Valerianaceoe. 

 Increased by seeds and division. 



Valefianella : Corn-Salad. 



Vallisneria (Eel-Grass). Hydrocharitacece. 



Propagated by the runners at the base of the leaf-tuft. 



Vallota (Scarborough Lily). Amaryllidacece. 



Increased by bulbels, which usually appear above the surface of 

 the pot ; also by division of the bulbs. 



Vanda. Orchidaceoe. 



The larger number of vandas are propagated in the same way as 

 described for Derides, but two species V. teres and V. Hookeriana 

 - both tall and quick growing, may be cut into lengths of a few 

 inches. The practice of the most successful cultivators is to start 

 them every year as cuttings about a foot long. See also Orchids, 

 page 372. 



Vanilla. Orchidaceoe. 



Propagation by division and cuttings. The vanilla of commerce 

 (V. planifolia) is propagated from long cuttings (from 2 feet to 12
