PROPAGATION OF ALPINE PLANTS 51 
lacerated root-stock lies dormant in the soil during the 
wettest period of the year and is apt to rot before new roots 
are formed. 
Strong growing plants may be replanted at the time of 
division, but plants with very fine growth, and those with 
fleshy, more or less tuberous roots are better potted for 
a while, because plants make fresh root more readily in a 
small body of porous soil with a pot around them than in 
the vast body of soil in the rockery or garden bed. 
By CutTTINGS. 
The next method of propagation is by cuttings, and in 
most cases where growth emanates from a central stem, 
branching out with auxiliary growths, and also where 
stalked growths spring from a tuft, this is the method to 
adopt. 
As examples of the former class we have the varieties of 
Phlox subulata, Zauschneria, Lithospermum prostratum, 
Onosma taurica, and Cheiranthus alpinus, etc. ; whilst the 
latter are typified by the Aubrietias, many of the Cam- 
panulas, Viola cornuta, V. gracilis and the Mimulus tribe. 
The Helianthemums, Cistus, Muehlenbeckia, are of com- 
paratively hard-wooded growth, and the ripened shoots of 
the current season, stripped off witha “heel” in early 
autumn, root best placed round the edges of pots or shallow 
pans. The softer growth of the sub-shrubby plants should 
be taken in spring when the new season’s growth is active ; 
and the other class, such as Campanulas, Aubrietias, should 
first be cut back to induce new growth, and the new shoots 
taken as cuttings when two or three leaf-joints have formed
