 most desirable bush, hardy in central New York and 

 Ontario. It is sometimes grown as a standard by being 

 worked on Plum, but it is then short-lived. Both this 

 and P. Japoniea are commonly worked on Plum, but 

 better results are to be expected from own-rooted plants 

 (got by layering or root-grafting).

 as an ornamental tree, but chiefly for the nuts (or pits 

 of the fruit). There are double-fld., white-fld., and 

 variegated-lvd. forms; also weeping forms. Var. macro- 

 carpa is an early-blooming erect-growing form with fls. 

 2 in. across and very showy. See Almond.

Much like the Almond in botam i and by

generally agreed to be an oriL.-irial j i, hhI to be 

 native to China: Ivs. broad-lanceolate or olilmigliinceo- 

 late, coarsely serrate: fls. solitary, pink, appearing be- 

 fore the Ivs. : fr. soft, pubescent at maturity, the stone 

 deep-pitted and very hard. Widely cultivated, especially 

 in North America, where it thrives under a great variety 

 of conditions.— There are two well-marked forms, the 

 clingstones or pavies (Persica vulgaris of Risso), and 

 the freestones {Persiea domestica of Risso). There are 

 many ornamental forms of the Peach tree: double-fld.
