quisitions, especially in .hybridization with other 

 groups: Type, Baltimore Belle. Fig. 2154. 



Alpine or Boursault. Native of the Swiss Alps; 

 semi-pendulous, long, flexible, smooth shoots: flowers 

 in large clusters: mostly purple or crimson flowers. 

 Good for pillars, very hardy, especially suitable for 

 shady places; should be well thinned in pruning, but 

 the flowering wood left alone : type Amadis. Pro- 

 duced by crossing Teas and R. alpina. 

 Garden-group 6. Multiflora. The Multiflora group 

 divides itself naturally into the Multiflora true and 

 Polvantha. R. multi flora, the parent type, is charac- 

 teristic of the varieties here, the flowers being produced 

 in large corymbs and continuing over a comparatively 

 long time. This group is particularly well adapted to 

 the wild garden. There are many hybrids, which are

 This picture was made from the White La France. The origi- 

 nal La France is pink. 



known in cultivation under the general term of Ram- 

 bler Roses. 



The Polyantha section has given a fairly hardy 

 variety in Crimson Rambler. Useful as pillar and 

 trellis Roses and respond to high cultivation. In 

 pruning remove only the old canes, leaving the young 

 new growth to carry flowers next year. Some cluster 

 Roses of the Indica or Tea alliance popularly called 

 Polyanthas do not belong here. 



Garden-group 7. Evergreen. The so-called Evergreen 

 Roses hold their foliage until very late in the year and 

 In hybridization appear likely to yield varieties which 

 are practically evergreen. 



Sempervirens, useful as pillar Roses, producing 

 flowers in corymbs: very hardy: vigorous growth: 

 free bloomer: requires considerable thinning in prun- 

 ing. Types, Felieite perpetuella. 



Wichuraiana (Fig. 2155), most popular of all the 

 rampant Roses: very hardy: growing in any soil: 

 this promises to be the basis of a very valuable race 

 Of American Roses: flowers in the type white. Hy-

brids have been raised from Hybrid Perpetual and 

 Tea varieties giving large flowers, scented; such are 

 Gardenia and Jersey Beauty. {Several hybridists are 

 now working on this species, and he next few years 

 promise remarkable developments. W. A. Manda in 

 New Jersey, M. H. Walsh in Massachusetts and M. 

 Horvath in Ohio are thus engaged. 



Cherokee (If. leevigata) of the southern states can 

 be grown satisfactorily away from its native regions 

 only in a greenhouse. Figs. 2152-4. 



The Banksian ( R. Banksice). Two varieties of 

 this are known, the yellow and the white. Requires 

 greenhouse treatment: evergreen: needs very little 

 pruning, merely shortening the shoots that have 

 bloomed. Yellow variety scentless, white variety pos- 

 sessing the odor of violets: flowers are produced in 

 graceful drooping clusters. 



Garden-group 8. Pompon. A small-flowered Provence 

 Rose. See No. 1. 



Garden-group 9. Hybrid Perpetual, or Hybrid Re- 

 montant. A large and comprehensive group of much- 

 mixed origin. The mixture with other groups has be- 

 come so involved as to render separation practically 

 impossible. The characteristics may be described as 

 stiff, upright growth, sometimes inclined to pendulous: 

 fls. of all types: foliage dull green, wrinkled, not shiny: 

 embracing generally the characteristics of the Provence, 

 Damask, French and the Chinese groups: fls. largo, in- 

 clined to flat, generally of dark colors. By far the 

 largest and most comprehensive division. Figs. 2168-9. 

 Garden-group 10. Hybrid Teas form a section of 

 the Hybrid Perpetual group crossed back on to the Tea- 

 scented China, gradually losing all identity. They dif- 

 fer from the pure Hybrid Perpetuals by having foliage 

 of a deeper green and less wrinkled. Some of the best 

 forcing Roses are in this group, which promises the 

 greatest development for American rosarians; Robert 

 Scott is a type of this class and is raised from Mer- 

 veille de Lyon, H. P., and Belle Siebrecht Hybrid Tea. 

 The La France type belongs here. Fig. 2170. 



Garden-group 11. Moss. A perpetual flowering 

 group of flie Provence. See Summer Roses and Fig, 

 2157. 



Garden-group 12. Bourbon. Dwarf and compact 

 growth, with rounded, more or less shining leaflets: 

 very floriferous: brilliant colors: good outline: in per- 

 fection late in the season: requires close pruning. Type, 

 Hermosa (or Armosa). 



Garden-group 13. Bourbon Perpetual. Very flor- 

 iferous: flowers moderate-sized, well formed, in clus- 

 ters. Type, Madame Isaac Pereire. 



Garden- group 14. China. The China or Monthly 

 Rose is characterized by its positively perpetual man- 

 ner of flower. Its blooms become much darkened in 

 color from the action of the sun's rays: fls. small and 

 irregular in shape. Somewhat tender. Chiefly interest- 

 ing as the parent of the true Teas. 



The Tea-scented China or Tea Rose. Fig. 2171. 

 Large, thick petals, with the characteristic tea scent: 

 flowers generally light colored, pink and creamy yel- 

 low: growth free; the best for forcing. The group 

 has been hybridized with all other sections and the 

 Tea influence is seen throughout the Rose family. 

 Some of the varieties are climbing. Type, Bon 

 Silene and Homer. 



Lawrenciana. Dwarf forms, requiring the same 

 treatment as the Teas. Commonly known as the 

 Fairy Rose. 



Garden group 15. The Musk. Very fragrant: rather 

 tender: derived from Rosa moschata : fls. of pale color. 

 This group has been much hybridized with others, and 

 its identity is lost as a garden plant in that of its deriv- 

 atives, especially the Noisette. The flower buds are 

 elongated and the flowers produced in clusters. 



Noisette. Fig. 2172. Larger flowered than the true 

 Musk Roses: flowering very late: free growth: more 

 hardy. The group bears a certain superficial resem- 

 blance to the Teas and requires moderate pruning; 

 will grow in any soil. This sub-group has been 

 largely blended with the Teas and with a loss of har- 

 diness. In consequence it has fallen into disuse. 

 Garden-group 16. Ayrshire. Perpetual forms of the 

 Ayrshire. For characters, See Summer Roses.
