RUDBECKIA, L. CONE-FLOWER. 

 (Composite.) 



The Rudbeckia Golden Glow has come into prominence so rapidly that other 

 good kinds have, in a measure, been forgotten, but attention should be drawn to the 

 great merits of such species as R. maxima, R. speciosa (Newmanni) and 

 R. subtomentosa, all of which are very desirable. Rudbeckia nitida would be classed 

 among the best plants also if it did not bloom when there are so many good yellow 

 flowering perennials which are a little better than it. The cone flowers all do best in 

 a moist situation, but thrive well under average conditions. Most of the species 

 increase rapidly and are easily propagated by division. The genus Echinacea is 

 closely allied to the Rudbeckia, and the best species, E. purpurea, is often sold under 

 the name of Rudbeckia purpurea.
