ROSE 



ROSE

Sempervirens, useful as pillar roses, producing 

 flowers in corymbs: very hardy: vigorous growth: 

 free bloomer: requires considerable thinning in pru- 

 ning. Types, Felicite perpetuella. 



Wichuraiana (Fig. 3440), 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. Hybrids 

 have been raised from Hybrid Perpetual and Tea 

 varieties giving large flowers, scented; such are 

 Gardenia and Jersey Beauty. Many hybridists have 

 worked on this species, and the past few years have 

 thoroughlj- made good the early promise of remark- 

 able developments. 



Cherokee (Rosa laevigata) of the southern states 

 can be grown satisfactorily away from its native 

 regions only in a greenhouse. (Figs. 3458, 3459.) 



The Banksian (Rosa Banksix). 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 Prov- 

 ence rose. See No. 1. 



Garden-group 9. Hybrid Perpetual, or Hybrid 

 Remontant. A large and comprehensive group of much- 

 mixed origin. The mixture with other groups has 

 become so involved as to render separation practically 

 impossible. The characteristics may be described as 

 stiff, upright growth, sometimes inclined to pendulous: 

 flowers of all types: foliage dull green, wrinkled, not 

 shiny: embracing generally the characteristics of the 

 Provence, Damask, French, and the Chinese groups: 

 flowers large, inclined to flat, generally of dark colors. 

 By far the largest and most comprehensive division. 

 (Figs. 3462, 3463.) 



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, Hybrid Perpetual, and Belle Siebrecht, 

 Hybrid Tea. The La France type belongs here. (Fig. 

 3464.) 



Garden-group 11. Moss. A perpetual-flowering group 

 of the Provence. See Summer Roses and Fig. 3442. 



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 florif- 

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

 ters. Type, Madame Isaac Pereire. 



Garden-group 14. China (Rosa chinensis). The 

 China or Monthly rose is characterized by its posi- 

 tively perpetual manner of flower. Its blooms become 

 much darkened in color from the action of the sun's 

 rays: flowers small and irregular in shape. Somewhat 

 tender. 



The Tea-scented China or Tea Rose (Fig. 3465), 

 Rosa odorata, is an allied species. It has large thick 

 petals, with the characteristic tea scent : flowers gen- 

 erally light-colored, pink and cream y yellow: growth 

 free; the best for forcing. The group has been hybri- 

 dized with all other sections and the Tea influence is 

 seen throughout the rose family. Some of the varie- 

 ties are climbing. Type Bon Silene and Homer. 



Lawrenceana. Dwarf forms, requiring the same 

 treatment as the Teas. Commonly known as the 

 Fairy Rose. 



Garden-group 15. Pernetiana. Crosses of Hybrid 

 Teas and "Austrian" brier. Habit generally like Hybrid 

 Teas but more vigorous, with stout spines and coarse 



3463. Paul Neyron rose. A good rose-colored variety of 

 the Hybrid Perpetual type. ( X \i) 



shiny foliage. The chief distinction, however, is in the 

 remarkable coloring of the flowers, which is indescriba- 

 ble, but often spoken of as "shrimp," with blendings 

 and shadings of burnished copper. Tendency to shed 

 foliage unless grown on almost pure clay. Some forms, 

 as Juliet, show affinity to Austrian in resenting prun- 

 ing, but later kinds are closer to Tea. Type Madame 

 Edouard Herriot. 



Garden-group 16. The Musk. Very fragrant: rather 

 tender: derived from Rosa moschata: flowers of pale 

 color. This group has been much hybridized with 

 others, and its identity is lost as a garden plant in that 

 of its derivatives, especially the Noisette. The flower- 

 buds are elongated and the flowers produced in clusters. 

 Noisette (Fig. 3466). Larger flowered than the 

 true Musk roses, flowering very late: free growth: 

 more hardy. The group bears a certain superficial 

 resemblance to the Teas and requires moderate prun- 

 ing; will grow in any soil. The subgroup has been 

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

 iness. In consequence it has fallen into disuse. 

 Garden-group 17. Ayrshire. Perpetual forms of the 

 Ayrshire. For characters, see Summer Roses. 



Garden-group 18. Perpetual-flowering varieties of the 

 Multiflora group. The term in gardens is taken to 

 include a large number of small cluster-flowered, 

 climbing roses, and is particularly important in Ameri- 

 can rose-culture, as the basis of a new section of 

 hybrids with the Teas and (erroneously) including 

 hybrids of Wichuraiana and Teas. M . H. Walsh in Mas-
