LIST OF PLANTS 179 
making a second leaf. An intermediate house tempera- 
ture is desirable while in a young state, but when well 
established they do very well in cold frame or ordinary 
greenhouse. The young seedlings may be expected to 
commence flowering in July and August. Special sorts 
are best increased by leaf-cuttings, planting small pieces 
with midrib round the margins of pots in a warm house. 
Young plants will also grow from the base. 
SWEET PEA.—See Lathyrus. 
SWEET WILLIAM.—Sow seed in April in a sunny 
position outside, thin out and transplant in September 
to where they are intended to flower the following year. 
SYMPHORICARPUS (SNOWBERRY).—Suckers of these are 
freely produced, and, if taken off with a few roots 
attached in autumn or spring, are a ready means of 
propagation. Cuttings of firm shoots, 6 to 8 inches 
long, may be planted in a shady border in September, 
and seed from the white berries may be sown when ripe. 
TacsoniA.—Propagate by cuttings, about 4 inches 
long, taken off with a heel and inserted under a bell- 
glass in spring or summer, or by seed when obtainable. 
TAMARIX.—Cuttings of these, taken in September, 
strike fairly well under a hand-glass in a shady north 
border. 
TARRAGON.—This herb is in frequent request for 
salads, for seasoning, and for making Tarragon vinegar. 
Divide the roots and replant in spring. Cuttings taken 
when growth is commencing will strike with a little 
warmth. 
Trecoma.—Propagated by cuttings of either young or 
partly-ripened shoots, by layers, and by root-cuttings. 
THALICTRUM.—These perennial plants are increased 
by division in early spring.
