or runners; dwarfs and mediums, should have their separate spots, 

 and independent treatment. It is much hetter to select a few promi- 

 nent, than to run into a great variety. We can hy this arrangement 

 procure plants much cheaper from the growers, or raise them by 

 cuttings or layers, which is simple enough to those who will devote 

 a litle patience or time to the subject, or those who prefer to begin 

 at once, and with the return of the plant season might, we think, 

 procure in May sorts in quantity at 12 to 20 cents each

MANDEVILLA SUAVEOLENS. 



Much and deservedly as this splendid climber is prized wherever it is pro- 

 perly cultivated, it is nevertheless perfectly unknown in many places, a 

 statement which may seem incredible to some, but which is strictly true. The 

 lady owner of an elegant and well kept conservatory recently expressed 

 surprise at seeing the Mandevilla rambling about the roof of a house in 

 which she was standing, and covered with its deliciously fragrant clusters of 

 snowy white Convolvulus-like blossoms; she said, "We tried it in the stove, 

 but we could not afford it sufficient space, and it was not very satisfactory ; 

 we therefore did not think that the conservatory would be warm enough for 

 it." And a correspondent, evidently an intelligent person, writing so re- 

 cently as the 10th inst,, from one of the principal towns of the kingdom, 

 begs for such information respecting- it as plainly indicates that it is not com- 

 monly grown in his locality. Had it not been his request to be informed 

 whether this, the best of conservatory climbers, is worth growing, I should 

 not have selected it as the subject of an article ; and I do so now more for the 

 purpose of recommending it to notice than to give especial directions for its 

 culture. As minute instructions may, however, operate as an inducement 

 to some amateurs to add the plant to their collection (and there are few 

 plant houses in which a suitable place for the Mandevilla might be found,) 

 I have thought it worth while to give them. 



It is not very suitable for pot culture, at least I believe it is not ; for ex- 

 cept the two first plants I had of it, I have never attempted to grow it in 

 this manner. I am convinced, however, from the success which 1 obtained 

 with those, that it may be made to bloom rather freely in a pot } and the fra- 

 grance and beauty of the flowers render it worth an effort to obtain them in 

 that manner. Were I to attempt its culture in pots, I would treat it as fol- 

 lows ; and although the display of blossom which I might get would be poor 

 compared with what plants turned out in the conservatory border, and al- 

 lowed plenty of space to ramble about, would produce, it would nevertheless 

 be ample compensation for the little attention which the plants would re- 

 quire. 



I would procure good strong young plants, say in March, prune them 

 back closely, leaving but one joint of the last season's growth ; then place
