174 Account of the Culture of the Rosa Banksiae. 



to what I trained against the wall. This wall being fourteen 

 feet high, and seventeen feet long, was completely covered 

 by the branches in the summer of 1819, some of them 

 extending full forty feet; this vigorous growth and the 

 subsequent production of blossoms, far exceeded all my 

 expectations. In the spring of this year, the plant broke 

 at every eye of the preceding year's wood, each shoot pro- 

 duced at its extremity, an umbel of flowers, which began 

 to open in April, and the whole wall was completely covered 

 with blossoms until the middle of June. 



" Before I discovered the proper method of treating it, 

 this Rose, from its early and vigorous growth, had always 

 suffered from the cold winds and frosts to which this country 

 is subject in March and April; this injury, however, I 

 have now ascertained, may be prevented by the following 

 treatment : it should be planted in a rich sandy loam, against 

 a wall exposed to a south or west aspect ; its branches must 

 be nailed close to the wall, in the manner usually practised 

 in training Morello Cherries, and when the wall is covered 

 to the extent proposed, all the strong shoots must be cut 

 out as they appear ; this will give strength to the remaining 

 branches intended to produce flowers in the succeeding 

 spring, which they will do most freely. 



" I also discovered, this season, a method of making small 

 plants of the Rosa Banksiae blow well in pots, after the 

 whole blossom of the trees against the wall had ceased, and 

 as this is likely to be successful, it is without doubt worthy 

 of notice. 



" In the beginning of February, I put several small plants 

 of the Rose in pots, on the back bed, in the house in which
