THE FORCING OF ROSES. 17 



Although it is claimed by some that the former is sub- 

 ject to black spot in the summer and fall, with us it has 

 very handsome, clean foliage, and the flowers are large, 

 full, very fragrant, and of a rich, deep pink color. Its 

 petals are rather thick, and it is a good keeper. With 

 some growers the stems are inclined to be short and weak. 



Mrs. P. Morgan is a promising sport from Mad. 

 Cusin. It is a stronger grower, a freer bloomer, and 

 the flowers are larger and darker. They are inclined to 

 be irregular in shape and variable in color. Both of 

 these roses will do well at about fifty-eight degrees. 

 The latter is injured if the house is damp, and if dull 

 weather comes when the house is wet from recent syr- 

 inging, the results to the flowers may be serious unless 

 the air can be dried. For this reason a steam heated 

 house is desirable. 



For growing at low temperatures, among the best of 

 the old kinds arc Wootton for red, Perle as yellow, 

 Bridesmaid as a large pink, and Mad. Cusin for small, 

 with Bride, or Niphetos for white. 



Perle is perhaps more extensively grown than any 

 other variety, and has no rival as a yellow sort. It 

 requires a moderately light soil, not too rich in unde- 

 composed manure, and an abundance of sunlight, with 

 a temperature of about sixty degrees. If the soil is 

 heavy, the houses should be at least two or three degrees 

 warmer than this. If any or all of these conditions are 

 r.ct given, this variety is very apt to furnish what 

 are known as "bullheads," and on this account many 

 growers have become dissatisfied with it, but can find no 

 other variety to compare with it. Care in securing a 

 soil that is not too rich, and in keeping up a tempera- 

 ture a little higher than is required by most of the other 

 sorts, will generally give satisfactory results. 



Niphetos is an old white sort, but, excepting Bride, 

 it has no equal, as it thrives and gives large numbers of
