CHAPTER X. 
PLANTING OF FLOWER SEEDS. 
PROPAGATION OF PLANTS. 
"PLANTS are reproduced in two ways, by seeds and 
vegetatively. 
Vegetative propagation is the multiplication of a plant 
by taking some portion of its root, stem or leaf and grow¬ 
ing a new plant from this portion. “Slipping” house plants 
is a common form of vegetative propagation. 
Some plants have been propagated vegetatively for so 
many generations that they have practically lost their 
ability to produce seed. Others can only be propagated 
true to the type of the parent plant by vegetative means. 
Hence the recommendation concerning certain Perennials 
in the lists of flowers that plants be purchased, for only 
the florist and nurseryman have the facilities for exten¬ 
sive vegetative propagation. 
STARTING FLOWER SEEDS IN-DOORS. 
The seeds of flowers recommended in this publication 
can be successfully sown directly out-of-doors, where the 
description of the seed indicates that the plant is grown 
from seed. But much quicker and more satisfactory re¬ 
sults can be obtained with most flower seeds if they are 
first started in-doors in pots or flats, except perhaps Cos¬ 
mos and Annual Poppy, which should be sown directly 
out-of-doors. Seeds started in-doors a month before the 
time they are usually planted out-of-doors and later trails-
