Rose (see also Rosa). The queen of flowers; woody plants, some of them distinctly shrubby, many forms much developed horticulturally, all grown for the beautiful and mostly fragrant flowers in white, yellow, and shades of red. See also Rosa.
Rosa (ancient Latin name). Rosaceae. Rose. Ornamental shrubs chiefly grown for handsome flowers, also for ornamental fruits and attractive foliage.
Deciduous or sometimes evergreen, upright, less often climbing or creeping shrubs with usually prickly sts.: lvs. alternate, odd-pinnate, rarely simple, stipulate (Figs. 3430, 3431): fls. solitary or corymbose at the end of usually short branchlets; petals and sepals 5, rarely 4; stamens numerous; pistils numerous, rarely few, inclosed in an urn-shaped receptacle, which becomes fleshy and berry-like at maturity, containing several or many bony achenes, usually erroneously called seeds; the fr. itself is called a "hip." Rosa is a widespread genus, easily distinguished by well- marked characters from allied genera, but in the limits of the genus itself the characters are exceedingly variable and it is very difficult to group into sections and species the innumerable forms which often pass gradually into each other. In no other genus, perhaps, are the opinions of botanists so much at variance in regard to the number of species. While some, as Bentham and Hooker, estimate the number at about 30, the French botanist Gandoger actually describes from Eu. and W. Asia alone 4,266 species. The larger number of liotanists recognize over 100 species. The roses are almost equally distributed through the colder and temperate regions of the northern hemisphere, in Amer, extending to N. Mex., in Afr. to Abyssinia, and in Asia to India. The fls. show a remarkable tendency to become double, and such forms have been known and cult, from time immemorial. These innumerable garden forms, increasing every year, are almost exclusively of hybrid origin and are therefore omitted in the botanical classification of the genus.
Many attempts have been made to subdivide the genus with more or less satisfactory results; the more important are those by A. DeCandolle, Lind- ley, Regel, and Baker. Nowadays the arrangement proposed by Crepin is considered the most natural and satisfactory and has been followed in the account given below. No good general monograph has been published since Lindley's " Monographia Rosa- rum" (1820), except a rather short one by Regel in 1877. Of the more recent publications the most important are those of Crepin, especially his "Primitiae Monographiae Rosarum." In consulting his publications one has to bear in mind that the author changed his opinion somewhat respecting the value of the species during his studies of the genus. In his later publications he takes a broader view in regard to the specific value of the rose forms and unites under one species many forms which he formerly considered as distinct species. An illustrated monograph valuable for the knowledge of the older garden forms and species is Thory and Redoute's "Les Roses," with 160 colored plates (1817-20). It is quoted below as Red. Ros. As the first edition in folio is found in only very few libraries, the smaller edition is cited in parenthesis by volume, groups and the sequence of the plates, neither pages nor plates being numbered continuously in this edition. The most recent book on roses is Miss Ellen Willmott's "The Genus Rosa," with about 150 excellent colored and numerous black plates; in this work all the important species of roses, including most of the recently introduced Chinese species and the types of our cultivated garden forms, are described and figured. It is quoted below as W. R. (with the number of the species).
The economic properties of the rose are of little importance. The most valuable product is attar of roses, a highly fragrant essential oil. It is chiefly manufactured in southeast Europe and western Asia from Rosa alba and R. damascena, and of late this industry has been successfully transplanted to Germany. See Perfumery Gardening, page 2547. The fruits of some species, especially of R. villosa and R. canina, are made into preserves.
The roses are mostly low or medium-sized shrubs, usually with prickly stems, often more or less stolonif- erous, sometimes climbing or creeping, with small or medium-sized odd-pinnate deciduous or evergreen foliage and with mostly large and showy, solitary or clustered flowers ranging in color from purple, crimson, or pink to white and yellow, and followed by ornamental usually scarlet or bright red fruits remaining on the branches a long time, sometimes through the whole winter. There is probably no flower more popular and better known than the rose. From tune immemorial poets have sung its praise, and the love of it can be traced through the most ancient documents in the literature of the Aryan race. It is remarkable to note, however, that the rose has played a far inferior part in the horticulture of the Chinese and Japanese. It is probably the first flower known and cultivated in a double state, and it is the double-flowered garden form whose image the word "rose" almost invariably brings to the mind, while to the wild single-flowered roses much less attention has been given. The ornamental value of single roses is rarely fully appreciated. The wild roses have a simple charm and graceful beauty of their own. No doubt the bold and dominating beauty of the double roses has eclipsed the more modest attractions of the single roses. The longer blooming season of the garden roses is also a factor in their favor. Though the wild roses cannot, perhaps, be compared with their more noble sisters of the garden, they are nevertheless fully able to rival other ornamental shrubs for the adornment of park and plot. Most of the species are hardy or almost hardy North; among the hardiest are R. rugosa, R. virginiana, R. Carolina, R. acicularis, R. blanda, R. Woodsii, R. heliophila, R. palustris, R. rubri- folia, R. pendulina, R. canina, R. cinnamomea, and R. pomífera. Hardy at least as far north as Massachusetts are R.-spinosissima, R. rubiginosa, R. multiflora, R. Helens, R. arvensis, R. setigera, R. gallica, R. setipoda, R. omeiensis, while others, as R. Wichuraiana, R. sern- pertrirens, R. sericea, R. fœtida, R. hemisphserica, require some shelter or protection. Hardy only South are R. Banksix, R. bracteata, R. chinensis, R. Lsevigata, R. odo- rata, R. stellata. The recently introduced species from central and western China have not yet been sufficiently tested, but a large percentage appears to be hardy as far north as Massachusetts.
According to the habit peculiar to each species, they can be used for a variety of purposes. Most of the species are shrubby, rarely exceeding 6 or 8 feet, and may be used for borders of shrubberies or for covering slopes and rocky ridges, especially R. rugosa, R. Carolina, and various American species. Some kinds, a be as R. rugosa and R. virginiana, make handsome ornamental hedges. The climbing species are used for covering walls, trelliswork, arbors, porches, or pillars, but perhaps display their beauty to the most advantage when allowed to ramble over shrubs or rocks. The half- evergreen R. Wichuraiana makes a beautiful ground- cover and may also te used for edging groups and flowerbeds. The fruits of most species are decorative and often remain on the branches all winter. The red sterna of most of the species of the Carolina and Cinnamomeio groups are effective in winter also. The foliage of most of the American species turns purple-orange or yellow in autumn, and so does that of It. rugosa, which is, in regard to the foliage with its dark green leathery and glossy leaves, the handsomest of the hardy roses.
With few exceptions the roses are of easy cultivation and grow in almost any kind of soil, except in a loose and very sandy one. They are readily transplanted. The wild roses need little pruning; they should only be thinned out and the weak and old wood be removed; long and vigorous shoots should not be shortened, especially in the climbing varieties, as these shoots are the most floriferous.
All true species can be propagated by seeds, but as roses are likely to hybridize, only seeds taken from isolated plante ought to be used. The hips should be gathered as soon as ripe, the seeds washed out and sown at once or stratified and sown in spring. They germinate the first year, but if kept in the hips during the winter and allowed to become dry, they usually do not germinate until the second year. Mice are very fond of the seeds. Almost all species grow readily from cuttings of nearly ripened wood in summer under glass. Many species, especially the climbing roses, can be propagated by hardwood cuttings taken in fall and planted in spring. Layering is less often practised, except with a few species, like R. foetida and R. hemisphaerica, which do not grow readily from cuttings. Some species, especially those of the groups of Cinnamomeae, Carolinae, and Gallicae, can be increased by root-cuttings; the roots are taken up in fall, stored during the winter in sphagnum or sand in a frost-proof room, and sown in spring in drills and covered about 2 inches deep. The species of the last-named groups and some others are also often increased by suckers and division. Budding and grafting is less often done with the wild roses and should be avoided for roses in shrubberies where the individual plants cannot be carefully watched; the stock usually throws up suckers and outgrows the cion, often in a short time.

Rose (see also Rosa). The queen of flowers; woody plants, some of them distinctly shrubby, many forms much developed horticulturally, all grown for the beautiful and mostly fragrant flowers in white, yellow, and shades of red.
It been been said that the garden rose does not thrive in North America as it does in Europe; but however true this may have been, it scarcely holds today. 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 horticultural 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). It is essential to success, however, that the intending rose- grower have a clear understanding of the main horticultural groups and the kinds of varieties in them, and this information is provided in Barron's article, beginning on page 3001.

Rose organizations.
The American Rose Society was organized in New York, March 13, 1899. "to increase the general interest in the cultivation and improve the standard of excellence of the rose for all the people," to organize a system of exhibitions, and otherwise to foster, stimulate, and increase the production in every possible way of improved varieties of the rose, suitable to our American climate and requirements." The Society is a clearinghouse for those interested in roses.
