Saintpaulia ionantha (saintpaul-ia, after Herr Saintpaul. Ord. 

 Gesneraceae). A pretty little warm-house plant, growing only about 

 4 ins. high, and producing violet flowers late in summer. Loam and 

 leaf mould in equal parts, with sand, make a good compost. Leaf 

 cuttings root readily if inserted in moist sand and cocoa-nut fibre 

 refuse and put into a warm case ; when rooted they may be potted 

 singly and subsequently transferred to 5 -in. Leaf cuttings may 

 be taken at different seasons to insure successional flowering. There 

 are several varieties, differing in tint. 



Salads. See Kitchen Garden. 



Salisburia. See Ginkgo. 



Salix, Willow (sa-lix, from sal (Celtic), near, and Us, water. Ord. 

 Salicineae). Hardy deciduous trees, of rapid growth in moist places, 

 and therefore suitable for planting at the waterside. Propagation 

 is by cuttings and seeds. To get good drooping plants the pendu- 

 lous forms may be grafted on tall stems. Alba, the White Willow, 

 has several varieties, of which vitellina and v. pendula are good. 

 Caprea is the common Sallow or Goat Willow ; the drooping variety 

 of this, pendula, is the Kilmarnock Willow. Elegantissima has 

 drooping branches. 



Sallow. See Salix. 



Salpiglossis (salpigloss-is, from salpinx, a tube, and glossa, a tongue, 

 in allusion to the style. Ord. Solanaceae). Beautiful plants, the 

 most valuable species of which is sinuata, from which have been 

 derived the splendid annuals offered by seedsmen. The flowers are 

 large and the colours are rich. The habit is loose and graceful. 

 They are best treated as half-hardy annuals (see Annuals), and may 

 be planted in beds or borders in May or June. They are also good 

 for pots; in this case, flower them in 5 -in., using a compost of loam 

 and decayed manure, with sand. Linearis, 

 purple, August, i ft. (syn. Petunia inter- 

 media), is a half-hardy perennial. 



Salsafy or Salsify (Tragopogon porri- 

 folium. Ord. Compositae). See Kitchen 

 Garden. 



Salvia (sal-via, from salvo, to save, in 

 allusion to medicinal qualities. Ord. 

 Labiatae). The Salvias are among the 

 most brilliant of flowers, and are parti- 

 cularly useful for giving bright masses of 

 bloom in winter. The best species for 



this purpose is splendens (Botanical PROPAGATING SALVIA SPLEN 

 Register, t. 687), herbaceous, of which DENS BY CUTTINGS IN LATE

 such as Bruantii, compacta, grandiflora, r . Drainage. 2. Soil, 

 and Silver Spot. They bloom most pro- 

 fusely. Salvia patens, an evergreen, gives us a lovely shade of 

 rich, shining Gentian-blue (Botanical Magazine, t. 3808). This 

 is a summer bloomer. It is so nearly hardy that it may be
