Winter Flowering Roses

These are varieties that tend to be once-bloomers in the temperate zone, but which will bloom more-or-less continuously during the winter under suitable conditions. Others may bloom all year, but are much better (larger, fuller, better colored and/or more fragrant) when flowering in winter.

It [Isabella Sprunt] is as variable as Safrano. The higher the temperature, the fewer the petals. In hot weather, not only do the blooms have fewer petals, the petals have less substance and lustre. The blooms tend to be smaller and pass from bud to spent bloom very quickly. In cooler weather it all happens more slowly. The blooms tend to be larger, they have many more petals and the petals are more substantial and lustrous. In our climate (hot summers, mild winters) both Safrano and Isabella Sprunt produce their fullest and loveliest blooms in winter

I had more interesting results from the cross R. chinensis minima (Tom Thumb var.) x R. banksiae lutescens and its reciprocal. The series of hybrids obtained varies from the dwarf ones of about eight inches to the big climbing ones; some thornless, all having good ornamental foliage. The blooms are white, in corymb, long lasting and very decorative.

A climbing plant which seemed to have no everblooming habit has now improved giving a profusion of sweetly scented double flowers which, from December till July, form a candid cascade. During the August-November period the luxuriant glossy foliage compensate for the lack of flowers. [Purezza]

Hybrid Perpetual Roses
Georgia Torrey Drennan

Undoubtedly the most popular rose of the class has been Gen. Jacqueminot. The color of this rose is unrivaled, and had it really claims to ever-blooming qualities its popularity would be unbounded. Unfortunately, it blooms only in spring, with now and then a few fall flowers. There is, though, one claim to favoritism that compensates for the lack of ever-blooming, and that is its capacity for winter blooming. Jacqueminot forces as readily as an Easter Lily. The florists manipulate it with great freedom, in the greenhouse, and striking indeed are the velvety, rich red Jacqueminot buds in contrast to wintry surroundings of snow, ice, and bare and leafless trees.

EVERBLOOMING HYBRID REMONTANT ROSES
Georgia Torrey Drennan

General Jacqueminot, among famous roses of the world, was the most distinct and celebrated member of this family until the appearance of the American Beauty. Charitably granted the weakness of blooming but once a year, paradoxical yet true, both General Jacqueminot and American Beauty must be accorded high place among everbloomers. They simply reverse the season. Their bloom time is winter. Florists find them as constant during the winter months as the Teas during the summer. They supply the cut roses of winter under the heaviest demands of society. Under glass, they make the winter garden brilliant.

Belle Portugaise

A glorious climbing rose with a prolonged season of bloom. I saw it blooming intermittently from October thru April in Belmont, CA.

Bengale d'Automne

Buds tend to fall off in spring/summer, blooms fully in autumn.

Rose Hedges in the South of France
M. André

Rosa indica major is almost naturalised throughout the whole of this region. It possesses the additional claim to favour of flowering nearly all the winter, forming beautiful hedges of dark green shining foliage, from which thousands of clusters of lovely flowers rise, of a tender delicate transparent pink, or almost pure white, with a brighter tinge in the centre and at the tips of the petals.

CHRISTMAS ROSES
Thomas Rivers

EVERY cultivator of the rose is well acquainted with the difficulty of having roses in bloom in the 'dark and dreary' month of December. I feel, therefore, much pleasure in giving the result of some experiments ending in perfect success; so that, in future, a bouquet of roses on Christmas-day may grace the festive board in company with the holly, rivalling in brilliancy the colour of its berries. The Bourbon Rose, Gloire de Rosamène, is now well known by every lover of this favourite flower as a most brilliant and beautiful variety; but, like many other roses remarkable for the brilliancy of their tints, its flowers are deficient in fullness; in fact, they are merely semi-double, and, like all roses of this description, they fade very quickly in hot weather: it is only in the cool cloudy days of autumn, when their flowers never fully expand, that they are seen in perfection. This quality induced me to turn my attention to this variety, as well calculated to give a crop of very late autumnal or winter flowers.

Nothing can be more simple than their management. Towards the end of May, young plants from small pots should be shifted into 6-inch pots, in a good compost of two-thirds loam and one-third rotten manure or decayed leaves, and plunged in sawdust or old tan in the open ground, fully exposed to sun and air. They may be allowed to bloom freely all June and July, but in August and September every blossom-bud should be pinched off; this will make the plants stout and very robust, and towards the end of October an abundant crop of incipient flower-buds will be apparent; the plants may then be removed to a light and airy glazed pit or greenhouse, and placed as near the glass as possible. No fire-heat, unless frost is very severe, should be employed, and abundance of air—they cannot have too much—should be given: it will also be much better to place the pot on slates or on a layer of sand, rather than on a dry wooden shelf. I am induced to recommend sand from the perfect success I have had with my plants, which, after being taken from the bed in which they had been plunged all the summer, were placed on sand: they put forth roots from the bottoms of the pots into the sand, grew luxuriantly all November, and commenced blooming in December. On January 4 I cut a most beautiful bouquet of flowers. I may add, that, if large plants can be procured, they may be potted into 8-inch pots, and in process of time, into 12-inch; so that large bushes covered with flowers may ornament the drawing-room in that month above all others, in which roses are 'rich and rare'—December.

At present I know of only three or four other varieties equal to the above as Christmas roses. These are all varieties with thin petals which in the warm rose-tide of June, soon fade. L'Etoile du Nord is one of the most desirable. This is a new variety, a seedling from General Jacqueminot, which gives its large globular crimson flowers very freely in November and December; their fragrance is then delightful. Triomphe des Beaux Arts and Oriflamme de St. Louis, of the same parentages are also charming winter roses, to which we may add our old favourite General Jacqueminot, which, under the same management, will bloom very nicely. In addition to this valuable quality, I had almost forgotten to add that the flowers of these free-blooming and not very double roses, although almost odourless under the bright sun of June, in winter exhale a delicate and agreeable perfume.

BEDDING ROSES
Donald Beaton

For filling up the bottom of a rose-wall, Gloire de Rosamene is the best of all Roses; and for making bouquets of Roses in bud from September to Christmas the Rosamene and Old White China are the best;

Parsons: Winter Roses (1847)

THE ancients possessed, at a very early period, the luxury of roses, and the Romans brought it to perfection by covering with beds of these flowers the couches whereon their guests were placed, and even the tables which were used for banquets; while some emperors went so far as to scatter them in the halls of their palace. At Rome, they were, at one time, brought from Egypt, in that part of the year when Italy could not produce them; but afterwards, in order to render these luxuries more easily attainable during the winter, by the leaders of the ton in that capital city of the world's empire, their gardeners found the means of producing, in green-houses warmed by means of pipes filled with hot water, an artificial temperature, which kept roses and lilies in bloom until the last of the year.
