berry* and the blackberry,f however, propagation by 

 suckers is the most convenient method, and it appears 

 to be followed by no bad results (Fig. 81). 



348. Propagation by Stolons. A stolon is a branch 

 that starts above or at the surface of the ground and 

 either grows prostrate or curves downward till it reaches 

 the ground where it takes root, usually at the nodes 

 (115). The currant, juneberry, cranberry and many 

 herbaceous plants are readily multiplied in this way. 

 Stolons often root without assistance, but the rooting is 

 much hastened and encouraged by covering the branch 

 with soil. When well rooted, the young plants may be 

 separated from the parent by cutting the stolons. 



Woody plants grown from stolons are seldom uniform 

 in size and are not often as well rooted as those grown 

 from cuttings (358). Some herbaceous plants are, how- 

 ever, more readily propagated by stolons than by any 

 other means. 



The offset by which the houseleekj is so readily prop- 

 agated, is a very short stolon that forms a single tuft of 



leaves at its apex.
