has made shoots this season more than six feet in length, and thick as a 

 moderate sized cano ; its leaves are enormous, and measure from the base 

 to the tip 9 inches, leaflets 3.;^ by 2 inches ; its large clusters of (lowers are 

 produced with from ten to fifteen in each, but as these are often too much 

 crowded to expand properly, it is better to thin each cluster, removing 

 about half the buds ; the flowers of this truly gigantic rose, are of a pe- 

 culiar deep rich red, sometimes tinted with purple ; they are variable ac- 

 cording to the season, but their prevailing color is as described. Budded 

 on stoutstocks of the Dog Rose, this variety will form a large umbrageous 

 tree, it will form also a line pillar rose, and as a bush budded on a two- 

 feet stem, so that the whole plant is taken at once by the eye : it will give 

 a magnificent mass of flowers at one view. — Id. pp. 52 and 53. 



We copy the following account of the new double Yel- 

 low rose. This variety flowered in our collection this 

 spring, and is truly a superb yellow rose. 



Persian Yellow Rose. — A new yellow rose has been given to us from 

 that land of flowers, Persia. This was introduced to the gardens of the 

 Horticultural Society of London, in 1838, and is now called the Persian 

 Yellow Rose. In habit it is so exactly like the Single Yellow Austrian 

 Briar, as not to be distinguished from it : it seems to grow readily budded 

 on the Dog Rose, as my plants this season have made shoots three feet or 

 more in length : in color it is of a deeper yellow than Rosa Harrisonii ; 

 its flowers are quite double, cupped, and not so liable to become reflexed 

 as that very pretty and brilliant rose. Like the Yellovv' Austrian Briar, 

 it loves a pure air and rich soil, and will probably bloom as freely. It 

 bloomed beautifully in the garden of the Horticultural Society, even on a 

 very small plant in a pot. — Id. pp. 74 and 75. 



The yellow Harrison is highly esteemed in England, 

 and is considered one of the handsomest of this family : no 

 French or English seedling has yet been produced equal 

 to it. 



Management of Perpetual Roses. — This tribe of roses is 

 likely, in our climate, to become exceedingly valuable. In 

 the middle Stales, and at the South, where all the Uourbon 

 and a great variety of the Chinese, Tea and Noisette roses 

 stand the winters without injury, hardy perpetual roses are 

 of less value: but in our climate we cannot rely upon a 

 good autumn bloom unless we plant the perpetuals. It is 

 true, the tender kinds will bloom freely till winter, if taken 

 up every fall and planted out every spring; but this is too 

 much trouble in some collections, and the disrooting every 

 year greatly reduces the abundance and size of the flowers; 

 if they could stand out, and take deep root in the soil, as 

 they do in the South, they would be scarcely known as the
