62 NEW MODE OF PROPAGATING HERBACEOUS PEONIES. 



The third division consists of Rosa villosa rubiginosa, moschaeta 

 alba, damascena, and canina : the roses of tins division have much 

 stronger roots than the others, and strike much deeper into the earth. 

 The place of their growth in their wild state is among large, strong 

 growing shrubs and trees : they therefore require a much stronger and 

 deeper soil, and a less airy situation than the two former divisions, and 

 they do not need nor bear so much pruning of the shoots. 



The fourth division consists of Rosa avensis, sempervirens, Banksiae, 

 and multiflora. These roses, in their natural state, trail along the 

 ground, or support themselves by bushes growing near them, they 

 therefore do not. require a very airy situation. 



The fifthj division consists of Rosa semperflorens and indica. The 

 sudden and rapid way in which these roses send forth their shoots 

 immediately on a change of cold to heat, points them out as growing 

 in their wild state on mountains covered with snow a part of the year, 

 and like other natives of such places, with rapidity, taking advantage 

 of an interval of warmth to grow, bloom, and ripen their seed. 



ON PROLONGING THE FLOWERING SEASON OF 

 CAMPANULA PYRAMIDALIS. 



BY MR. THOMAS DOWELL, OF AMINGTON HALL. 



WnEN properly managed the Campanula pyramidalis is one of the 

 most charming ornaments of the floral tribe, especially when grown in 

 pots, either for the summer ornament of the greenhouse, sitting-room, 

 verandah, or terrace. I find many previous testimonies to the same 

 purport are recorded in the volumes of this Magazine. There are, too, 

 particular directions given as to the method of treatment by which 

 specimens of extraordinary size and beauty have been produced. Sucli 

 being the case I do not think it necessary that I should here enter upon 

 the same ground. There is, however, one particular which will give 

 even additional interest and value to this fine blooming plant, viz. to 

 extend the period of its floral display. This I am glad to state can be 

 done, and as it is said " great effects result from little causes," by the 

 following very simple process : 



In the year 1849 I had a fine plant which commenced blooming in 

 July, and its season of great beauty was extended up to Christmas. 

 This was effected by regularly cutting off the decayed flowers, so as to 

 prevent the production of any seed. As above remarked, the plant 

 made a. fine display until Christmas, and even in January and February 

 1850 it had some blossoms. The operation is easily done, and the 

 result will most amply repay for the attention.
