THE NURSERY-LIST 439 



Water-Cress (Roripa Nasturtium). Crucifercs. 



Propagated by cuttings of the young stems, which root in mud 

 with great readiness, or seeds scattered in the water or mud. 



Watermelon (Citrullusvulgaris). Cucurbitacece. 



Propagated by seeds, usually sown where the plants are to remain, 

 after the weather is warm and settled ; frost-tender. 



Watsonia. Iridacece. 



Multiplied by seeds and by offsets 



Wigandia. Hydrophyllacece. 



Propagated by seeds started indoors in January, and also by 

 root-cuttings. 



Wineberry (Rubus phcenicolasius) . Rosacece. 



Increases readily by " tips," the same as the black raspberry 



(see Raspberry} ; also by root-cuttings. 



Wisteria (often spelled Wistaria). Leguminosce. 



Readily grown from seeds ; sometimes increased by division ; also 

 cuttings of ripened wood, usually handled under glass. The common 

 purple and white kinds are largely grown from root-cuttings an 

 inch or two long, placed in bottom heat, when they will start in 

 four or five weeks. Many of the fancy kinds, especially when wood 

 is scarce, are root- or crown-grafted on W. sinensis. A good method 

 of propagation is by layers, to which the plants are well adapted. 



Witloof (Cichorium Intybus). Composites. 



A form of chicory, grown for the blanched young shoots. To 

 produce roots for winter and spring forcing, the seed is sown in the 

 open ground in spring as soon as the weather is warm. The roots 

 are lifted before freezing weather in fall, the leaves trimmed to a 

 crown 2 inches long, and stored till wanted. 



Wormwood (Artemisia Absinthium). Composites. 



Hardy perennial, grown from seeds sown as soon as ripe or the 

 following spring; old plants may be divided. See Artemisia, 

 Tarragon. 



Xanthoceras. Sapindacece. 



Commonly multiplied by seeds, stratified and sown in spring; 

 root-cuttings in moderate bottom heat are sometimes used.
