Culture. — These plants are raised in different methods, according 

 to the kinds. 



The first sort is best propagated by parting the roots and planting 

 them out in moist, sheltered, shady situations, either in the autumn 

 or spring. 



In the second kind the plants are best raised by sowing the seeds 

 in pots of good mould in the autumn, protecting them by means of 

 a frame and glasses during the winter. When the plants have some 

 growth they may be removed into separate pots, and placed in the 

 open air duiing the summer, but brought under the shelter of a 

 green-house or garden-frame in the winter; the latter is probabl}- 

 the belter practice. 



They may likewise be increased by planting cuttings of the young 

 shoots in a warm shady spot during the sununer. These, when the) 

 have formed good roots, should be removed into pots, to be protected 

 under glasses during the winter. 



They require a pretty full exposure to llie air when the weather 

 is suitable, being sufficiently hardy to stand the open air in mild 

 winters. 



The third and fourth species may be raised by sowing the seeds 

 in the early spring months, in a bed of earth in an open exposure, 

 or in pots. When the plants have attained sufficient growth they 

 should be removed into a spot of fresh light earth, and planted out 

 six inches apart, proper shade and water being given, till they be-
