178 THE NURSERY LIST. 



Ash. See Fraxinus. 

 Asimina. Anonacecz. 



Propagated by seeds. The seedlings may be raised in 

 pots, and sheltered carefully. By layers made in autumn. 



Asparagus. Liliacecz. 



The common kitchen-garden asparagus is best propa- 

 gated by means of seeds. These are sown in spring as 

 soon as the ground can be worked, usually in rows a foot 

 or two apart. Thin the young plants to 2 or 3 inches 

 apart in the row and give good culture, and the plants 

 can be set in the field the following spring, and they will 

 give a fair crop after growing there two seasons. Small 

 growers nearly always buy plants of nurserymen. Old 

 asparagus crowns can be divided, but seeds give better 

 plants. 



The ornamental species of asparagus are propagated 

 by seeds when they are obtainable ; otherwise, by divi- 

 sion. See Myrsiphyllum. 



Asperula. Rubiacecz. 



Increased by seeds and by divisions of the roots dur- 

 ing spring and early summer. 



Asphodeline. Liliacecz. 



Propagated by division. 

 Asphodelus (Asphodel). Liliacece. 



Propagated by seeds and by division of the root in 

 early spring. 



Aspidistra. Liliacetz. 



By division of the crowns, or by suckers. 

 Aspidium. See under Ferns. 

 Asplenium. See under Ferns. 



Aster (Aster, Starwort, Michaelmas Daisy). Composite. 

 Propagated by seeds sown in spring, or by root divi- 

 sions made in autumn ; also by cuttings, which root freely 

 in sandy soil under a hand-glass, with little heat. For 

 China Aster, see Callistephus. 



Astilbe. Saxifragacece. 



Propagated by division in early spring, and by seeds 

 if they are produced.
