PLANTS WORTH GROWING 87 
seed may be sown in Autumn, the best place for 
raising seedlings at this season being a cold frame. 
As soon as the second pair of characteristic leaves 
are formed the seedlings should be pricked out, and 
when the plants are about three inches high the 
central shoot should be pinched in order to encourage 
the production of side-growths. Where the soil is 
fairly light and well drained, and the atmosphere 
clean and free from smoke, the young plants may be 
planted out during October, but on cold wet soils 
and in large towns where Winter's rains and fogs 
bring down poisonous soot deposits which settle 
upon the leaves it is better to winter the plants in 
frames, and plant out in Spring. Grimy atmosphere 
and excessive dampness are more fatal to 
Antirrhinums than quite severe frost. Autumn- 
sown plants will begin to bloom by the beginning 
of June, and if the early flower spikes are cut before 
seed forms the plants will break into second growth 
and continue to bloom throughout Summer and 
Autumn. 
Another batch of seed may be sown in a moder- 
ately warm greenhouse in January or February, and 
if the young plants are kept growing without a 
check, and gradually hardened off until the latter 
end of April, they will begin to bloom by the 
end of June, and from July onwards will make a 
glorious display. 
Although it is recommended that for ordinary 
stock seedlings should be relied upon, it may be
