Cult, The stove and greenhouse species of this genus grow 

 well in a mixture of loam and peat, and young cuttings will root 

 readily in sand, under a hand-glass in heat. The hardy kinds 

 or those natives of North America succeed well in a light rich 

 soil, and are increased by dividing at the root in spring, or by seeds.
