Rose-culture under glass is a practice which has been, if anything, rather neglected in gardens; and yet, perhaps, the gardener who has to supply cut-flowers for the house could not grow any one plant that is equal to the Rose for such purposes between January and June. The introduction of the Marechal Niel led to the extension of indoor Rose-culture, and, incidentally, to the trial of other varieties for planting out in houses; and at the present time a good few gardeners are extending their experience in that way. Pot Roses are useful for pot culture, but whether we consider the quantity or the quality of the flowers, there can be no doubt that planted-out trees succeed best from the middle or end of February. Here we have for some time back depended a good deal on the Rose in spring for cut-flowers; and now, from being scarce with us, if anything, for floral decoration, it has become a common practice, when other things happen to be scarce, to "make up with Roses" - in other words, the extra demand is provided for by the Roses, but we have never too many for house purposes or for giving away.

Our success with the Marechal Niel, like mostly all who have tried it anywhere round here, has not been satisfactory without frequent planting and renewals; and consequently we have for some years back taken to other varieties most extensively, and the three best of these are Gloire de Dijon, Cheshunt Hybrid, Souvenir d'un Ami, and a few others; but the two first - a light and a dark - are regarded as the best for our purpose. Two years last November we planted an old but strong standard Gloire de Dijon in one of the greenhouses, allowing it a few square yards for extension. The second year it bore several hundred blooms, and this season it has borne close upon 700, and all were good, large, and fine, many of them quite fit for exhibition purposes - the greater proportion being produced in March and April, but the house had to be kept as cool as possible to keep them back to that period. Another lesser plant, put in at the same time, and allowed to ramble up the gable of the house, has done equally well. From these two plants alone we have often had several hundreds of blooms standing in water in the fruit-room, because they were not wanted at the time.

A Cheshunt Hybrid covering a large space of the roof in the same house has bloomed contemporaneously with the Gloires, and produced a great quantity of flowers, and is still flowering at this date, June 8th. In addition to those used by ourselves in our own establishment, about eighty dozen blooms have been sent away during March and April to other people. Our outdoor Roses are late in flowering, and to succeed the early house plants we have just erected and planted a kind of lean-to orchard-house structure, 45 feet long, with all the best climbing Roses, which we propose training as methodically as Vines on the long-rod system, which answers admirably for Roses, especially the stronger-growing trees. I could at times have cut shoots of Gloire 15 feet or more in length, that were wreathed with flowers in all stages of development their whole length, so regular had the buds broken. It is the young annual shoots, however, that break best, no matter how long they are. In training, the original stems are led off horizontally along the bottom of the wall, and also along the front to the bottom wire, and from these shoots are led upwards, about 6 inches apart, just like young Vine-canes, and they are encouraged to grow as much as they will, and allowed the following spring to bloom their whole length.

When done flowering, every alternate shoot, at least, is cut down to a bottom bud, to insure plenty of wood at the base for the following season, and the others are allowed to extend till the space is filled. In order to furnish a house regularly with wood all over, some methodical system of training of this kind is necessary, and far more easily carried out than the haphazard method of taking shoots when they are formed, and scheming how and where to train them.

The varieties we have selected for indoor work, all good kinds, presenting distinct shades of colour, are Gloire de Dijon, Cheshunt Hybrid, Marechal Niel, Devoniensis, Madame Berard, Reine Marie Henrietta, Solfaterre, Madame Levet, and Souvenir d'un Ami. Before the planted-out trees flower, plants in pots are forced. J. S. W.
