Mr. Owen Thomas recommends for growing on walls in England the following varieties:
Green Gage Brandy Gage Denniston's Superb Gage Comte d'Athem's Gage Transparent Gage Transparent Late Gage Jefferson Reine Claude Violette Brahy's Green Gage Bryanstone Gage Oullin's Golden Gage Golden Transparent Gage Reine Claude de Bavay Coe's Golden Drop Kirke's Blue Washington
The bush fruits, so far as I know, are never cultivated as dwarfs. To speak more exactly I should say that no dwarf stock is ever used to reduce the size to which the plants grow. On the other hand, bush fruits are often systematically pruned back in order to restrict their size, and are sometimes trained in elaborate forms as dwarf fruit trees are. To this extent they are managed in the same way and might properly be treated in the same general category. What is more to our purpose, they are almost always included in the plan of any private fruit garden on a restricted area, such as we have had chiefly in view in this discussion of dwarf fruit trees. These reasons make it appropriate, if not indeed essential, that something should be said regarding these fruits here.
All bush fruits can be grown in such forms as cordons, espaliers, etc. Anything of this sort which the gardener wishes can become a part of his garden of little trees. Gooseberries and currants offer the most entertainment and remuneration when subjected to special pruning and training, and indeed they should not be omitted from any garden scheme of this kind. Raspberries are less amenable to this kind of education and should be introduced with some care. Blackberries are necessarily difficult to handle and no very complicated schemes of pruning and training can be successfully applied to them. Such other fruits as Loganberries, strawberry-raspberries, June berries, etc., may be introduced "at the owner's risk." Any of them will submit to a certain amount of correction with the pruning knife, and may add to the variety of fruits grown in the amateur's garden. Of course, it is distinctly understood that these special methods of treatment are not commercially recommended for any of the bush fruits in America.
