golden-yellow ; this variety needs no recommendation. Reve ' 

 d'Or, deep yellow ; a grand and hardy variety. W. Allen 

 Richardson, deep orange; now a well-known favourite. 



Bourbon Roses (Rosa indica boarboniand). 



These Roses are very sweet-scented, and are remarkable for 

 the second crop of flowers being the best. They are supposed 

 to have resulted from a cross between R. indica and R. gallica, 

 and are a remarkably free section of the Monthly Roses. Intro- 

 duced from the Isle of Bourbon about 1825. 



This is a pretty class, and if not pruned severely, the plants will 

 flower most abundantly in the autumn. The following varieties 

 can be recommended : Armosa, pink; this makes a bold effect 

 if planted in a mass. Climbing Souvenir de la Malmaison, light 

 flesh colour; very fine and free. Madame Isaac Pereire, light 

 carmine ; very pretty and a free grower. Mrs. Paul, rosy- 

 peach colour ; an excellent and beautiful variety ; good, grower. 

 Souvenir de la Malmaison, flesh colour ; large ; a well-known 

 popular variety. 



Rosa Polyantha hybrida. 



This belongs to the Rosa multiflora group, some sections 

 of which are very dwarf, as in the present case, while others are 

 tall climbers, as in the case of Crimson Rambler. The flowers 

 are always small, and produced very continuously in large clusters. 



These lovely little Roses are not so well known as they 

 should be, or they would undoubtedly be widely ' planted or 

 grown in pots, as they succeed admirably both under glass and 

 outside, and their large trusses of small, graceful blossoms are 

 very useful indeed where cut flowers are wanted. If in pots, a 

 compost of four-fifths fibrous, rich loam and one part decayed 

 manure, with a little bone-meal added, will grow them well; 

 and if forced gradually — not given too much heat at first — and 

 kept close to the glass, it is astonishing how admirably they 

 grow and flower. Immediately a shoot has done flowering, 

 whether inside or outside, it should be cut down nearly to its 

 base ; fresh growth will then be made, and another crop of 

 flowers very shortly produced. In fact, by this plan several 

 crops of blossom will be secured from the plants during the 

 season. Another advantage the Roses of this section possess is 

 their dwarf habit, ift. to i8in. being the average height of the 

 plants when in flower, which renders them suitable for margins
