THE NURSERY-LIST 241 



tings are taken in January and placed in sand in bottom heat, 

 they root readily. 



Arctotis. Composites. 



Propagated by cuttings in mild heat. The commonly cultivated 

 kinds are tender annuals and may be raised readily from seeds 

 sown in the open when weather is warm, or started indoors. 



Ardisia. Myrsinacecs. 



Handled by seeds and cuttings. The latter should be taken 

 from young shoots of half-matured wood, and placed in a cutting- 

 bed with a top and bottom temperature of 70. The cuttings may 

 be readily obtained from old plants that have been cut back. They 

 should root in a month. Choose cuttings only from plants of good 

 berry-bearing habit. Cuttings give more compact or shorter 

 plants than seedlings. Seedlings give fruiting plants the following 

 year. Usually seeds are sown in late winter or early spring, and 

 plants are ready for potting in early summer. Seeds often 

 germinate slowly. 



Areca (Cabbage Palm). Palmaceas. 



Grown from seeds, which should be sown in a gentle heat and 

 kept moist. See Palms, page 377. 



Aregelia. Bromeliacece. 



Propagation as for billbergia, which see. 



Arenaria (Sandwort). Caryophyllaceoe. 



Propagated by seeds, division and cuttings ; the last placed 

 in a propagating-box or frame will root freely. Seeds should be 

 sown in spring in a coldframe. The best time to divide the plant 

 is early spring, or in summer after most of the growth is made. 

 Cuttings are employed for rare species or varieties. 



Arenga. Palmaceoe. 



Propagated by seeds. See Palms, page 377. 



Argemone (Argemony). Papaveracece. 



Propagated by seeds, which may be sown outdoors in spring 

 where they are to stand or else started in a hotbed. 



Argyreia (Silver Weed). Convolvulacece. 



Handled by cuttings, which will do well in sand under glass, in 

 gentle bottom heat. May also be increased by seeds, when obtain- 

 able.
