332 THE NURSERY LIST. 



Viburnum. Caprifoliacecr. 



Seeds, whicli should be stratified. They usually remain 

 dormant the first year. Layers usually make the best- 

 plants. Green cuttings made in summer and handled in 

 frames give excellent results. V. tomeniosum ( W plica- 

 tuin of nurseries) is propagated by cuttings. Ripe cut- 

 tings are sometimes used for the soft-wooded species. 

 The snowball or guelder-rose {V. Opiihis) is rapidly in- 

 creased by layers. It is also a good stock for closely re- 

 lated species. V. Lantana and ]'. dentata are good stocks 

 on which varieties difficult to handle can be worked by 

 the veneer-graft during winter.
