THE AUTUMNAL ROSE GARDEN. 179 



foliage and flowers, ornamenting the flower- 

 garden from three to four months in summer and 

 autumn : it also forms a very fine standard. 



It requires the burning sun of Italy to make 

 these roses produce their seed: yet, by perse- 

 verance and careful cultivation, this desirable end 

 may be obtained. To raise a double variety of 

 Rosa Hardii is, at any rate, worth attempting. 

 A flued wall must be used to train the plants to ; 

 and in small gardens, where there is not such a 

 convenience, a hollow wall might be built, about 

 four or five feet in height and ten or twelve feet 

 long, of two courses of four-inch brickwork, with 

 a space between, into one end of which an Ar- 

 nott's stove might be introduced, and a pipe 

 carried in a straight line through to the opposite 

 end (each end must of course be built up to keep 

 in the hot air) ; this pipe would heat the air be- 

 tween the two courses of brickwork sufficiently 

 for the purpose. A fire should be kept every 

 night from the middle of May to the middle of 

 July ; and this treatment would possibly induce 

 some of these roses to give their seed. Rosa 

 Hardii would bloom freely if trained to a hot 

 wall ; and, if fertilised with the Double Yellow 

 Briar, seed may perhaps be obtained. Lucida, 

 with the Yellow China Rose, will also be an ex- 

 periment worth trying. Maria Leonida, fertilised 

 with the Tuscany Rose, might also give some
