 Lvs lanceolate or oblong: fls. in terminal, usually few- 

 fld spikes; bracts persistent, 1-fld. ; calyx long-tubular, 

 slit down one side; corolla-tube slender, as long as 

 calvx or longer; lateral segments spreading; lateral

ROSE (see also Rosa). The article Rose will probably 

 be consulted oftener than any other in this Cyclopedia. 

 Therefore, the subject is presented from many points 

 of view, even at the risk of repetition. Every pains 

 has been taken to procure reliable information and ad- 

 vice from specialists in the different parts of the sub- 

 ject. It has been said that the garden Rose does not 

 thrive in North America as it does in Europe; but how- 

 ever true this may have been, it scarcely holds to-day. 

 The success of the Rose in this country is very largely 

 a question of the selection of adaptable varieties. These 

 varieties are mostly the compounds of various types and 

 species. In most garden Roses it is now impossible to 

 trace the original species with accuracy. For horticul- 

 tural purposes, a purely botanical classification is of 

 minor consequence, although, in the main, the leading 

 garden-groups follow old specific lines. For a garden 

 classification that follows botanical lines closely, see 

 Baker in Gardener's Chronicle, II. 24, p. 199 (1885.). 



The leading contemporaneous American text on the 

 Rose is Ellwanger's. American Rose books are: "The 

 Rose Manual," Robert Buist, Philadelphia, 1844, and 

 later editions; "Manual of Roses," William Robert 

 Prince, New York, 1846; "The Rose," Samuel Parsons, 

 New York, 1847, and later editions; "American Rose 

 Culturist," New York, 1856; "Book of Roses," Francis 

 Parkman, Boston, 1866; "The Rose," Henry Shaw, St. 

 Louis, 1882; "The Rose," H. B. Ellwanger, New York, 

 1882, 2d ed. 1892; "Secrets of Rose Culture," W. J. 

 Hatton, Huntington, N. Y., 1891. For a list of Rose 

 books in all languages, see "Bibliografia de la Rosa," 

 by Vergara, Madrid, 1892.

Horticultural Classification of Roses. The garden 

 classification of Roses presents considerable difficulty, 

 as the several groups have been so much mixed that 

 the original characteristics of each overlap at nearly all 

 points. This is particularly true of the Perpetuals, of 

 which any close classification is impossible. The diffi- 

 culties increase as one advances. Certain clear-cut 

 characters may be taken to mark certain distinct groups 

 in the summer Roses, with which the horticulturist has 

 not busied himself so much. Nearly all of these char- 



ROSE 



acters are reproduced in the Perpetuals, and, being 

 blended together, give rise to endless confusion; thus 

 the following scheme is merely suggestive and should 

 be studied in comparison with the botanical classifi- 

 cation (see page 1548). 



American Rose culture, so far as garden varieties are 

 concerned, can hardly be said to have found itself as 

 yet. Our growers are to-day striving to overcome the 

 short-lived character of the blooms, so as to import into 

 our gardens something of the Rose beauty of Europe. 

 The Wichuraiana, Rugosa, and Multiflora Roses, com- 

 bined with our native species and blended again with the 

 best representatives of the garden groups already grown, 

 seem to offer the solution. The beginning has already 

 been made. The hot sun and trying climatic conditions 

 of our summers are fatal to the full beauties of the 

 Roses of France and England. The flower is developed 

 so quickly that it has no opportunity to "build" itself; 

 and once developed it fades as rapidly. What has been 

 done for other florists' flowers remains yet to be accom- 

 plished for the Rose, and the American Rose of the 

 future will have to be developed to suit the circum- 

 stances, in the same way that the American carnation 

 has been produced. A special society has been formed 

 to foster this work and is now in its third year of exis- 

 tence.
