TREE AND SHRUB LIST 215 



4 



SALISBURIA. (See Ginkgo.) 



SALIX. Willow. 

 SEEDS. Not used. 

 *GUTTINGS. Very easily rooted from hard wood cuttings. Set out 



in Spring. Propagate S. viminalis, S. triandra, S. cordata, and *S. 



purpurea (Forbyana) for tying nursery stock, some others break 



instead of bending. 

 GRAFTING. The Kilmarnock Pussy Willow, a variety of S. caprea, 



is frequently grafted on S. caprea to give stronger shoots. 



SAMBUCUS. Elderberry. 

 SEEDS. Grow readily. 

 * CUTTINGS. Best propagate the Golden Elder by hard wood cuttings, 



although it comes rather true from seeds. Other species may be 



rooted from hard or soft wood cuttings also. 

 ROOT CUTTINGS. Many of the sorts may be propagated by this 



method. 

 SUCKER. Readily propagated by this method. 



SASSAFRAS. 



*SEEDS. Ripen in Autumn; sow immediately or keep in moist earth, 



sowing in Spring. 

 SUCKERS. Start when roots are injured. 



SCHINUS. Sweet Pepper Tree. 

 SEEDS. Grow easily. 



SCIADOPITYS. Umbrella Pine. 



SEEDS. Very slow growing. Seed obtained from Japan. 

 CUTTINGS. More rapid than seeds but plants are not apt to be 

 symmetrical. 



SEQUOIA. (Giant Tree of California.) 

 SEEDS. 

 CUTTINGS. (See Thuya, page 217.) 



SHEPHERDIA. Buffalo Berry. 



SEEDS. Grow readily. As the sexes are distinct, seedling plants 

 must be grown until the sex can be determined. Seedlings are 

 rather sensitive to strong sun. 

 CUTTINGS. 

 SKIMMIA. 



SEEDS. By seeds both sexed plants are obtained, so that one waits for 



flowering to determine the berry producers. 

 CUTTINGS. Produce the plant exactly. Use half-ripe wood under 



SOPHORA. Japan Pagoda Tree. 



*SEEDS. Germinate readily when fresh. 



CUTTINGS. Hard wood or green wood; the latter are best grown 



from indoor plants. 

 GRAFTING. Varieties are grafted on seedlings of the type. 



SORBUS. Mountain Ash. 



SEEDS. Crush fruits and wash out the seeds; sow immediately or 



store in damp sand until Spring. 

 GRAFTING AND BUDDING. Varieties are grafted or budded on S. 



aucuparia, S. americana, or Cratsegus.
