sow at once. It is more usual to bury them in sand 
until spring, when the seed can be taken out and sown 
in shallow drills outside or in pans in a cold frame. 
Germination is usually very slow and irregular; some 
may come up the first season, and others not until the 
second year. The first flowers produced are no indica- 
tion of what the worth of the plants may be, so they 
should be grown on for another season to obtain a 
proper estimate of their value, or be budded on healthy 
stocks to hasten their development. 
Rusus.—The ornamental kinds, like those grown for 
their fruits, are propagated by cuttings, suckers, and 
division; also by pegging down the tips of long growths 
in July. 
SacE.—This herb, which is in frequent demand, may 
be raised from seed sown in March in gentle heat to 
plant out in May. Cuttings of growing shoots will root 
in sandy soil under a hand-glass on a shady border in 
spring. The easiest and most general plan is to pull off 
rooted slips and to plant them in a warm, dry border in 
April or September. 
SAGITTARIA (ARROW-HEAD).—Plants suitable for grow- 
ing in marshy ground and in shallow ponds are obtained 
by dividing old ones in March or April. 
SAINTPAULIA.—The charming little warm greenhouse 
_ plants S. ionantha and its varieties, sometimes called 
African Violets, are raised from seed similarly treated to 
those of Streptocarpus. Mature leaves treated like leaf- 
cuttings of Gloxinias will also grow. 
SALPIGLOSSIS.—Sow seed of these beautiful half-hardy 
annuals in gentle heat about the middle of March, and 
plant out in a sheltered, sunny position early in June. 
SALSAFY AND SCORZONERA.—Sow the seed in deep,
