20 ROSA BERBERIFOLIA HARDII. 



but it is a difficult matter to get soundly ripened buds, and 

 from their diminutiveness the operation is a very delicate 

 one, requiring to be executed with great nicety to succeed. 

 There are now in bloom here two or three plants that were 

 budded on the Dog-rose last September which have shoots 

 from 12 to 1 8 inches in length ; the tips of some I enclose 

 that it may be seen they are in perfect health. These will 

 be removed to a north wall and sheltered on the approach 

 of Winter. During the severe Winters of 1841-1842 some 

 scores of budded plants unprotected were killed here, and 

 the variety was, I believe, generally killed throughout the 

 kingdom ; since that time no stock seems to have been 

 established anywhere. With regard to its cultivation an, 

 airy and dry situation is the chief thing to be looked to. 

 It cannot endure much or continued wet ; under such cir- 

 cumstances mildew invariably attacks it, and I have seen 

 plants dead in November while others in a drier situation 

 have out-lived the winter and bloomed throughout the 

 following season. It cannot, however, be considered per- 

 fectly hardy, and should be placed in a cold pit or airy 

 situation in the greenhouse during winter, and kept close 

 to the glass, watering it sparingly. In the case of mildew 

 occurring, to which most Roses are liable, the plants should 

 be sprinkled with sulphur, and if attacked by green-fly 

 fumigated or washed with tobacco-water. About the be- 

 ginning of May they may be turned into the open ground, 

 sheltering for a few days in case of frosty or biting weather 

 that they may become gradually inured to their new situa- 

 tion. They thrive very well planted on raised rock-work 

 in a roughish soil of sandy peat, or, in fact, in almost any 

 dry open situation where not too much exposed to cutting 

 winds. Thus treated they will continually give forth their 

 flowers from July to the commencement of the autumn 

 frosts, when they may be taken up, potted in sandy peat 

 in pots well drained, and again placed in a pit or green- 

 house for the winter. If under any circumstances the 

 removal of the plants is not desired, a handglass may be
