SELECTING STOCKS. 233 



can Dogwood (0. florida), is the best stock upon which 

 to bud or graft its own varieties, or those of other 

 closely allied species. The herbaceous species, of course, 

 are not propagated by these modes. 



CORYLUS (Hazel or Filbert). The Hazelnuts are rarely 

 propagated by budding or grafting in this country, but 

 in Europe the weak-growing and dwarf varieties are 

 sometimes worked on the stronger. Seedlings of the com- 

 mon European Hazel (C. Avelland), it being one of the 

 most hardy and free-growing species, is preferred as a 

 stock. Seedlings are preferable to layers or cuttings, as 

 they have a better root system; that is, longer and stronger 

 side or brace-roots, as they are termed. 



COTO^EASTER. The deciduous species grow freely on 

 either Quince or Hawthorn stock, while the evergreen 

 species are usually propagated by layers or cuttings. 



CRAT^GCTS (Hawthorn, White Thorn). Seedlings of 

 any of the strongest growing species may be employed as 

 stocks for the double flowering and other varieties. For 

 cultivation in this country, stocks of the indigenous 

 species are preferable to the European. 



CYTISUS (Broom, Scotch, Spanish, etc.) The smaller, 

 trailing, or low-growing species may be grafted on stocks 

 of the stronger growing, or on the Laburnum, if stand- 

 ard plants are desired. 



DAPHNE (Spurge Laurel). The Daphnes are princi- 

 pally low-growing evergreen shrubs, rarely propagated 

 by grafting, but scarce species and varieties may be grown 

 on stocks of the common European Spurge Laurel 

 (D. Laureola). 



EUONYMUS (Spindle Tree, Burning Bush, Wahoo, etc.) 

 Seedlings of the larger and stronger growing species, like 

 the American Burning Bush (E. atropurpureus) , and 

 the European Spindle tree (E. Europceus), are often em- 

 ployed as stocks upon which to work the broad-leaved
