These plants are easily propagated, as they throw up suckers in abun- 

 dance. These should be left till well rooted, and then be taken off' and potted 

 in the material recommended above for established plants ; after which they 

 must be kept moist, and in the shade, until they make fresh roots. When 

 they become established, place them near the light, and apply more water 

 to the roots. What they principally require is coolness and moisture 

 at the roots, and a good season of growth during the winter months.
