"General Allard, a hybrid rose, from which Monsiem Laffay raised his perpetual rose, Madame Laffay, is much inclined to give a second series of flowers. This rose should be planted in a very warm border, or trained against a south wall with Bourbon Gloire de Rosomènes; and, if carefully fertilized with it, some beautiful crimson autumnal roses would probably be originated. Chênedolé may also be subjected to the same treatment. What a fine autumnal rose one like it would be!"--_Rivers._
_Rosa Spinosissima._--The original Scotch Rose is a wild dwarf rose, common in Scotland and the north of England. As it bears seed in great abundance, as these seeds vegetate freely, and as the Scotch gardeners have taken pride in multiplying and improving this native growth of the soil, the number of varieties is nominally immense. Many of them, however, are scarcely to be distinguished the one from the other. The flowers are small, and exceedingly numerous. They bloom earlier than most roses, and show various shades of crimson, rose, white, and yellow,--or rather straw-color; for the yellow Scotch Rose is apparently a hybrid. They are useful for covering banks and forming clumps where masses of bloom are required. Nothing can exceed their hardiness, and they increase abundantly by suckers. A list of named varieties of the Scotch Rose would, from their multiplicity, and want of distinctness, be even more unsatisfactory than the florist's lists of pansies or verbenas. The following, however, are good:--
La Neige is pure white, and very double. Guy Mannering is of a deep blush. Sulphurea, Lady Balllie, and the Marchioness of Lansdowne, are of a pale straw or sulphur color. The Yellow Scotch is of a deeper yellow tint. Flora, Daphne, Erebus, Venus, and the Countess of Glasgow, are of deep shades of rose and crimson.
"Scotch roses, when grown into beds and clumps as dwarfs, are beautiful; and in early seasons they will bloom nearly a fortnight before the other summer roses make their appearance. This, of course, makes them desirable appendages to the flower-garden. They bear seed profusely; and raising new varieties from seed will be found a most interesting employment. To do this, all that is required is to sow the seed as soon as ripe, in October, in pots or beds of fine earth, covering it with nearly an inch of mould: the succeeding spring they will come up, and bloom in perfection the season following.
