SELECTING STOCKS. 243 



ROBINIA (Locust or False Acacia). Seedlings of the 

 common Locust (R. Pseud acacia), are the best stocks for 

 the varieties of the species, as well as those of the Rose 

 Acacia (R. liispida). The latter and its varieties, when 

 grown on their own roots, produce suckers so freely that 

 they become a nuisance in the garden. 



ROSA (Rose). Many species and varieties are em- 

 ployed as stocks, and in Europe the Wild Dog Rose (R. 

 canina), is usually recommended for this purpose. The 

 wild plants as they are found in the hedges and woods 

 are used, as well as seedlings raised in the nursery. A 

 variety known as the Manetti is extensively employed as 

 a stock in this country, and appears to thrive better in 

 our climate than the Dog Rose, and for this reason is 

 usually preferred. It is readily raised by cuttings, .these 

 producing plants large enough for use the first season. 

 The common Sweet Briar (R. ruMginosa), which is a nat- 

 uralized species from Enropo, is also an excellent stock 

 for nearly all of the cultivated varieties. It is less likely 

 to produce suckers than the Manetti, and is exceedingly 

 hardy. 



SALIX (Willow). The varieties usually propagated by 

 grafting will, as a rule, succeed best on stocks of their 

 own species. The common Kilmarnock Willow being 

 only a variety of the English Goat Willow (8. Caprea), 

 the cions take more readily on this stock than on any 

 other. It will grow, however, on the Pointed-leaved 

 Willow (S. acuminata], also indigenous to Great Britain, 

 but the cions do not take as readily and freely, but 

 when they do unite, the union is quite perfect and lasting. 

 The so-called American Weeping or Fountain Willow 

 (S. purpurea pendula), is a trailing variety, of the 

 English Bitter Willow, and may be grafted on stocks of 

 either of the above-named species. 



SOPHORA JAPONIC A. The Weeping and Variegated- 

 leaved varieties are grown on seedling stocks of the species.
