THE NURSERY-LIST 421 



Solanum. Solanacece. 



The annuals, and most of the other species, are raised from seeds 

 sown where plants are to stand, or the foliage kinds started indoors. 

 The Jerusalem cherry (S. Pseudo-capsicum) is grown readily from 

 seeds ; also from cuttings. The tuberous kinds may be increased by 

 tubers, or division of them. The greenhouse shrubby plants may be 

 propagated by softwood cuttings in a frame. See Potato, Eggplant. 



Soldanella. Primulaceoe. 



Propagated by seed and division. 



Solidago (Goldenrod). Composites. 



Readily grown from seed, blooming the second year. Mature 

 plants may be divided in fall or spring. 



Sollya. Pittosporaceoe. 



Propagated freely by seeds, and by cuttings in sand under glass. 



Sonerila. Melastomaceoe. 



Multiplied by seeds ; also by cuttings in a frame in a house. Also 

 increased by leaves, giving the same treatment as for bertolonia. 



Sophora. Leguminosas. 



Increased by seeds, layers and cuttings of either ripened or green 

 wood. The named varieties are grafted on common stocks. 



Sophronitis. Orchidaceoe. 



Propagated by division, just as growth begins. See Orchids, 

 page 372. 



Sorbaria. Rosaceoe. 



Propagated by hardwood cuttings, root-cuttings, suckers and 

 seeds, as for spiraea, with which the group is sometimes united. 



Sorbus. RosacecB. 



Propagated by seeds sown in fall or stratified, and by layers. 

 Varieties are budded or grafted on allied species, usually S. Aucu- 

 paria, S. americana, and even on hawthorn. Sorbus is a polymor- 

 phous group, including the mountain ashes and service trees. 



Sorghum : Holcus. 



Sorrel (Rumex, several species). Polygonacece. 



Multiplied by seeds and division. The cultivated kinds are grown 

 as pot-herbs.
