or more, according to its size, one or two such shoots may be 

 taken from each plant for the purpose of propagation. 



Like most of the order it likes a strong rich but not 

 damp soil during the growing season ; when it has ceased 

 growing it may be taken up and treated like similar roots 

 during winter, care being always taken to keep them dry, 

 free from frost, and as much excluded from the air as possible. 



The plants in the garden of the Society were raised from 

 seeds collected by Mr. Hartweg in 1838, of which a large 

 quantity was distributed, with a label marked Co/ivolvulacea, 

 splendid, half-hard?/ ; a designation which the plant truly 

 merits.
