This species is a half hardy perennial, with tuberous 

 roots like the common Dahlia ; it grows from three to four 

 feet high, and requires the same treatment as that plant. It 

 may be raised from either seeds, cuttings, or divisions of the 

 old roots. The seeds should be sown about the beginning of 

 March on a moderate hot bed, and treated like seedling- 

 Dahlias ; the old roots should be potted about the end of 

 February and placed in the forcing-house, and the young- 

 shoots when about three inches long should be taken off and 

 treated in the same way as the Dahlia. They may be 

 planted in the open border, about the end of May or begin- 

 ning of June, and will flower from the beginning of August 

 to the end of September, or later if not destroyed by frost. 

 When the flowering is past the roots should be taken up and 

 either potted or packed in a box of dry old tan or mould, 

 and then put in some dry place secure from the frost during 

 winter.
