174 THE NURSERY LIST. 



Apricot [Primus Armeniaca, P. dasycarpa, P. Jniiiie). 

 Rosacea. 



The apricot thrives upon a variety of stocks. Apricot 

 stocl<s are used in apricot-growing: regions, especially for 

 deep and rich, well-drained soils. The pits grow readily if 

 given the same treatment as that detailed for the peach 

 (which see). The stocks are also handled in the same 

 manner as peach stocks. Apricots upon apricot roots are 

 not largely grown outside of California, in this country. 

 Apricot stocks can be grown from root cuttings the same 

 as cherries and other stone fruits. 



The apricot does well upon the peach, especially on 

 light soils. In the warmer parts of the country peach is 

 much used. 



Plum stocks are commonly used at the north, especially 

 if the trees are to be planted in moist or heavy soils. The 

 common jilum is generally used, but some of the native 

 plnm stocks are now coming into favor, especially in 

 trying climates. The Russian apricots, which are a hardy 

 race of Pninus Ariiieiiiaca, are grown in colder climates 

 than the common varieties, and they therefore demand 

 hardy stocks. Any of the nati\e plums make good 

 stocks, but the Marianna is now coming into especial 

 prominence. The myrobolan plum can be used for all 

 aoricots, but it is not popular, particularly in severe 

 climates. (See Bulletin 71, Cornell Experiment Station. ) 



The almond, both hard and soft-shelled, is sometimes 

 used for the apricot, but the union is likely to be imperfect, 

 and it is not recommended. Almond-rooted trees are 

 thought to be best adapted to light soils. 



Varieties of apricots are usually budded, in the same 

 way as the peach, although they may be side-grafted at 

 the crown in the nursery row. 



Aquilegia (Columbine, Honeysuckle erroneously). A'aiiiiii- 

 cn/acecF. 

 Increased by seeds. They must be sown verv thinly, 

 soon after being ripe, in a sandy soil or in pans in a cold- 

 frame. Division of the root is the only way to perpetuate 

 any particular variety with certainty. 



Arabis (Wall Cress, Rock Cress). Crucifcra;. 



Increased by seeds sown in the border or in pans, in 

 spring ; by divisions of the root, and by cuttings placed 

 in a shady border during summer.
