TO BLOOM THE DOUBLE YELLOW AND AUSTRIAN ROSES. 101 



the following Lobelias last spring, viz., Lobelia propinqua, L. longi- 

 folia, and L. grandijlora. They were put out in the open border when 

 the season permitted, and grew well, and flowered during the summer, 

 but on the approach of winter they were forgotten, and remained in 

 the open ground until the 19th of January last ; on that morning the 

 thermometer stood at 23° of Fahrenheit, (at 8 o'clock,) and was 

 probably a little lower during the night ; they were then taken up, 

 and laid in the vinery, where there was then no fire ; and they are at 

 this time in perfect health. The Lobelias stood in a south border 

 of a light soil, and of course were not very luxuriant.

TO BLOOM THE DOUBLE YELLOW AND AUSTRIAN ROSES. 



BY OBSERVER. 



The Yellow Rose (Rosa sulphurea) does not in general flower well, as 

 has been observed in some late numbers of the Cabinet ; it requires an 

 open eastern situation, so as that the young buds may receive the 

 early and gradual continuance of the sun, thereby avoiding its too 

 sudden effects, which proves so injurious when preceded by frost. It 

 delights in a rich loamy soil on a dry substratum, and to be supplied 

 with plenty of moisture, when in a growing state. Every autumn, or 

 immediately after the bloom is over, one-half of the old wood should 

 be cut down, within about four inches of the ground, and that which 

 remains should be divested of all old and superfluous shoots, retain- 

 ing, but shortening such as have flowered to a healthy bud and leaf; 

 all unripe shoots are to continue untouched till matured, then to be 

 shortened according to their strength. But this means a succession 

 of thriving blooming shoots will be kept up : all lateral buds, except a 

 few towards the extremity of such shoots, should be pinched off" when 

 discernible, in order to have them produce a massy head of flowers. 

 It sometimes happens that this and the Yellow and Austrian Roses 

 (R. lutea, and R. bicolor) flower" freely, though injudiciously treated. 

 Yet to depend on an annual supply of vigorous blooming plants, I would 

 strongly recommend the above practice, or that of budding them on 

 the common Chinese stock (R. Sinensis.) Should insects attack them
