 (A. Canadensis) almost every one is familiar. 

 under cultivation it nearly doubles in size. 

 There are numerous other American species, 

 but none so fine as the Rocky Mountain forms. 

 Many fine hybrids have been raised from these. 

 A cross with the white form of A. vulgar is on 

 carulea has produced a flower of similar form 

 to the latter, but of a pure snow-white color, 

 two of these seedlings yielding double white 

 flowers of the size and form of ccerulea. These 

 white forms, including the common white, are 

 among the most beautiful of all. A. glandu- 

 losa, the Altaian columbine, and the scarce A. 

 Stuarti, a hybrid between A. glandulosa and 

 A. Witmanni, are pronounced the finest of the 

 genus where they can be successfully grown, 

 both requiring moisture at the roots, with perfect 

 drainage. 



Of the several kinds of Hemerocallis seen in 

 gardens, none equals H. flava, the old-fash- 

 ioned and always beautiful " yellow lily." Why 

 the rusty-colored fulva should be cultivated at

 its place, is beyond comprehension ; yet country 

 yards and city gardens are overrun with this 

 coarse, spreading plant, whose flower is neither
