The genus Rudbeckia (called after Professor Rudbeck of Upsal 

 who died in 1 702) is a very ornamental one, its different species making 

 a gay appearance in the Autumn. R. hirta is perhaps one of the most 

 desirable, from its moderate size, seldom growing higher than two feet — 

 it was introduced about the year 1714, it is a native of N. America, 

 and is found on the mountains from Virginia to Florida — it likes a 

 light rich soil, and is propagated by parting the roots, which should be 

 done in the spring, as it flowers so late in Autumn as to prevent the 

 removal in sufficient time for the plants to be well established before 

 winter — it is rather tender, sometimes being destroyed by too much 

 wet. The following are pleasing species: — 



R. purpurea. 



— fulgida. 



— columnaris. 



— speciosa. 



— pinnata.
