It is an attractive topic, this of growing Grapes in greenhouses. Of course, the large grower, with his range of vineries, can afford to ignore it; but it is of real, practical interest to a very large class of people. The matter presents itself under two aspects: (1) the association of Grapes and permanent indoor plants; (2) combining Grape culture with plants which may be grown out of doors in summer, or in frames. Although I am familiar with instances which prove that plants may be grown permanently with Vines, I consider the other system far preferable. By limiting himself to a few popular classes of flowering plants, and procuring a select number of varieties of them, the amateur can give himself just as much pleasure as if he grew a hundred kinds - probably, indeed, far more. Here is a list of plants that may be associated with Vines:-
Arum Lilies (Richardias).
Begonias (tuberous). Bouvardias.
If an amateur got a select list of varieties of these, and grew them well, he would have quite enough to occupy his time, and he would have sufficient material to secure a long display of beauty. The Arum Lilies, Chrysanthemums, Pelargoniums, Roses, and Solanums would all do out of doors in summer. The Bouvardias, Calceolarias, Cinerarias, Cyclamens, and Primulas would be quite at home in a frame. As to the Begonias and Fuchsias, they do not object to a certain amount of shade, and would probably do very well under the Vines, but they could also be grown outside in summer. The great advantage of this plan is that it permits the amateur to give a single eye to the welfare of the Vines during their growing season, which is much more likely to conduce to his peace of mind, and to ensure successful results, than attempting to reconcile the conflicting interests of plants and Grapes. The winter- and spring-flowering plants which I have named would enliven the house when the Vines were at rest, and in the early stages of their growth, and they could be supplemented by Dutch bulbs. Moreover, "Geraniums," Lobelias, Dahlias, Cannas, and other bedders could be wintered in the house. If the plants named are not enough to exhaust the energies of the grower, he may bring in Acacias, Camellias, Daphnes, and Epacrises to fill up his time with. All could be made to thrive. It is not well to have many varieties of Grapes in a small house; indeed, it would be wise to confine attention to two - namely, Black Hamburgh and Foster's Seedling, or Buckland Sweetwater instead of the latter, if preferred.
