Varieties. In the bedding or dwarf section of Lobelias 

 there are numerous named varieties, which, however, are 

 frequently so near alike in colour as to be readily used as 

 substitutes one for another. L. speciosa is an old type 

 still largely grown, as it proves very useful for trailing 

 over vases, &c. L. pumila magnifica is one of the very 

 best blue varieties for any purpose. Cuttings must be 

 inserted for preserving the compact habit of any named 

 sort ; seedlings will not perpetuate such characteristics. 

 A list of other varieties is subjoined.
