CHAPTER VI 
PROPAGATION OF ALPINE PLANTS: THE 
VARIOUS METHODS DESCRIBED 
By DIvIsIon oF Roots. 
HE majority of alpine plants may be increased by 
division of the root clumps, for it is a prevalent 
habit with these plants of diminutive stature or of creeping 
or trailing habit to make clusters of crown growths each 
with individual roots, although intertwining in a much 
tangled mass, or to spread out jointed stems that take root 
wherever a joint rests upon the ground. To quote instances 
of plants of this character we may mention the Saxifrages, 
Sedums and Sempervivumsas of the clustered crowns type, 
and the prostrate Veronicas, Aczenas, Arenarias, and Aubri- 
etias of the stem-rooting type. Many of the Campanulas, 
too, are of tufted growth, the clumps parting into several 
portions with roots attached, and other plants of this 
character are the Armerias, Gentianas acaulis, verna and 
others, and most of the Primula tribe. All such plants may 
be lifted, carefully shaken to remove as much soil as possible, 
and gently pulled asunder, taking care not to pull the 
herbage from the root-stock, but so to separate the mass of
