Progress of Horticulture for 1844. 9 



ishing to see in what numbers seedlings are produced by the 

 Paris rose fanciers. The newest varieties will be found under 

 our floricultural notices ; among the number is a hybrid per- 

 petual moss. The Persian yellow flowered in our collection 

 last summer and is the most superb of all the yellow roses. 

 Chromatella or Cloth of Gold is a fine rose, but not quite 

 so yellow as Avas at first announced. 



The introduction of the several species of Achimenes has 

 been a decided addition to our stock of autumn flowering 

 plants. Splendid specimens of A. longiflora, grandiflora, 

 rosea, and pedunculata, were grown last season : two others 

 are now added, the A. hirsuta and picta, the former similar to 

 pedunculata, the latter, with brilliant scarlet and yellow 

 flowers, a.nd elegant shaded foliage. A. multiflora is yet 

 very scarce. With the gloxinias, a beautiful show of flowers 

 may be kept up in the greenhouse from July till October. 



The science of cultivation has been exemplified in the arti- 

 cles of Messrs. Tescheraacher and Russell, on the pelargonium, 

 each of which are worthy the careful perusal of all amateurs. 

 On the subject of charcoal and guano, and their application 

 to culture, Mr. Teschemacher"s papers are highly valuable. 

 The introduction of guano, will create great changes in the 

 growth and management of many kinds of plants, and those 

 who are trying experiments with it should turn to his article, 

 p. 140, for details of the mode of application. The results of 

 our own experiments have been most satisfactory ; and we 

 would recommend the use of guano, for improving and 

 strengthening the growth of all rapid growing plants. For 

 roses, pelargoniums, cactuses, verbenas, camellias, applied once 

 a fortnight, its effects have been truly wonderful. 



Landscape Gardening. 



There is a very decided improvement in the taste for the 

 embellishment of country residences ; a far greater variety of 

 trees and shrubs are selected for ornament, and in regard to 

 their arrangement there is more attention paid to picturesque 

 effect. In the vicinity of Boston, and New York, several 

 villa residences have been recently laid out, which, from the 

 taste of the proprietors, we have no doubt will be beautiful
