180 PLANT PROPAGATION 
THUNBERGIA.—Propagate the annual T. elata and 
varieties by seed sown in a temperature of about 65 
degrees in March; the shrubby and climbing stove kinds 
by rather firm cuttings inserted under a bell-glass in 
spring and summer, 
_ Tuymr.—Both the Common and the Lemon Thyme 
are in frequent demand for culinary purposes. Plants 
are easily raised by sowing seed in April on a warm, 
sunny border. If some fine soil is shaken in the tufts in 
autumn, they can be divided into rooted pieces fit for 
planting in March or April. 
THYRSACANTHUS (THYRSE FLOWER).—This distinct 
stove flowering plant strikes readily from cuttings in- 
serted singly in small pots in a close, warm frame with 
bottom heat in spring. 
Ticripta.—Once seen, the bright, gay, spotted 
blossoms of these greenhouse bulbs are never forgotten. 
Propagation is effected by offsets and by seed. Tigridias 
will grow in warm districts in sheltered, sunny situations 
outdoors in summer if planted with a little sand round 
the bulbs in April. 
TitianpsiA.-—The handsome bright-coloured stove 
species, such as T. Lindeni, T. psittacina, and T. 
splendens, are all increased by seed and suckers, the 
latter taken off when they get a little firm at the base. 
A moist heat of 85 degrees is suitable. 
Tomato.—Sow seed at the end of March or early in 
April in pots or pans of light sandy soil and plunge in 
gentle bottom heat. Insert the seedlings singly in 
4-inch pots when they have made two true leaves, grow 
on without check, and harden off to plant out in June. 
Where special houses are devoted to Tomato culture, 
other sowings are made in September and again in
