CANNA 



CANNA 



655 



have not sufficient durability to be very useful as cut- 

 flowers. As individual blooms, the flowers are not usually 

 attractive, but they are showy and interesting in the 

 mass and at a distance. The new race of Italian or 

 Flaccida cannas has more attractive flowers, but even 

 these are most useful when on the plant. 



It is impossible for the gardener to determine species 

 of canna in the common garden forms. In fact, the 

 species are little known except in herbaria and as wild 

 plants growing in their original habitats. The mon- 

 ographers do not agree as to the definitions of what 

 have been described as original or wild species. The 

 following account of species is included more for the 

 purpose of showing the range within the genus and 

 of making a catalogue of leading 

 botanical names than to set specific 

 limits or to indicate what species- 

 forms are in cultivation. The Crozy 

 experiments began with crossing C. 

 Warscewiczii with a variety of C. 

 nepalensis of gardens (C. flaccida?) 

 having large yellow flowers and very 

 long creeping tubers; and some of the 

 progeny was crossed with C. aureo- 

 picta (a garden form). The recent 

 attractive orchid - flowered cannas spring 

 largely from the C. flaccida forms.
