THE NURSERY-LIST 245 



Aster (Aster. Starwort. Michaelmas Daisy). Composites. 



Propagated by seeds sown in spring, and by root-division in 

 autumn or spring ; also by cuttings, which root freely in sandy soil 

 under a glass. In general, seeds grow freely. The common native 

 asters may be handled as seedlings or by division of stools. The 

 named garden asters (perennials) are increased by division and by 

 cuttings ; seeds may be used, but they may not reproduce the 

 variety. For China aster, see Callistephus, page 267. 



Astilbe. Saxifragacece. 



Propagated by division in early spring, and by seeds, if they are 

 produced, sown in early spring in the greenhouse. Division of the 

 plants in the common method. 



Astragalus (Milk Vetch). Leguminosoe. 



Grown from seeds, which germinate slowly ; stratification may 

 be advisable in some cases. Cuttings are sometimes used, struck 

 under gentle heat. Division may be employed if stools are large, 

 but divided plants often die. Seed propagation is to be preferred. 



Astrocaryum. Palmaceoe. 



Increased by seeds in spring under glass ; also by suckers, 

 when produced. See Palms, page 377. 



Atalantia. Rutacca. 



Handled by ripened cuttings, which root in sandy soil under a 

 glass ; also by seeds when obtainable. 



Atriplex. Chenopodiaccoe. 



Grown from seed with readiness; shrubby kinds also by soft 

 cuttings. See Orach, page 370. 



Aubrietia. Cruciferoe. 



Multiplied by seeds, layers, cuttings, division. Seeds may be 

 sown in spring in a frame. The slender branches may be layered 

 with good results. Cuttings may be taken from bright growing 

 shoots. 



Aucuba. Cornacece. 



Readily increased by seeds, sown as soon as mature ; and by 

 half -ripe greenwood cuttings struck under glass. The kinds propa- 

 gate by cuttings in a cool house. The varieties are sometimes 

 grafted on the common form in early spring, under glass. The 

 plant is tender at the North.
