PERENNIAL SUNFLOWERS, HELENIUMS, AND RUDBECKIAS 

 AT WISLEY, 1914. 



Report by C. C. Titchmarsh, Trials Officer. 



Forty stocks of Perennial Sunflowers were sent to Wisley in the 

 spring of 1914. The plants comprised Helianthus, 18 varieties ; 

 Helenium, 10 varieties ; and Rudbeckia, 8 varieties. They were planted 

 in a deeply-trenched and well-manured border on the north-east 

 side of the Iris Ditch. With one exception, the plants made excellent 

 growth and were in full flower when examined by a Sub-Committee 

 of the Floral Committee on September 25, 1914. 



The hardy herbaceous perennials known as Perennial Sunflowers 

 belong to the genera Helenium, Helianthus, Echinacea, and Rudheckia. 

 They are natives of North America, and Helianthus extends to 

 Peru and Chile. Although often confused, these genera present 

 sharply-defined characters, even in those species and their fonns 

 which are commonly cultivated. 



A full account of Helianthus is given by Mr. D. Dewar in this 

 Journal, vol. xv. (1892), pp. 26 et seq.
