 about two inches. Then cut them off, with a small piece of 

 the base branch adhering to the young wood ; or the shoots 

 may be cut off with one or several of these young branchlets 

 on them. Cut the old branch through at the base of each 

 young one, and insert the cutting with this heel of the old 

 wood entire. In this country, usually grown from common 

 green cuttings in summer. 



Cistus (Rock Rose). Cistinece. 



Propagated by seeds, by layers or cuttings under frames 

 outside, or inside with a gentle bottom heat ; but seedlings 

 always make the best plants. The seeds should be sown
