should have a slick set to support its branches when they have ad- 

 vanced a lillle. 



The fourth sort may be readily increased by sowing the seeds as 

 above, and by parting the roots and cuttings of the young branches, 

 planting them out in the open borders or other places where they 

 are to grow in the autumn, for the first method, and the spring for 

 the latter, giving water as there may be occasion. 



In the fifth sort, the seeds should be sown in pots of light earth 

 in the autumn, plunging them in a hot-bed frame during the winter. 

 When the plants have attained proper growth in the spring, they 

 should be removed into separate pots, which should be protected in 

 the following winter under a garden frame. And some may be 

 planted out in the open ground, where they often succeed in mild 

 w inters. 



The parted roots should be planted out in the spring, either in 

 pols or the open ground. 



The plants raised from seed are in general the best, as flowering 

 more strongly. 



By cutting down the stems of the plants in the first year of their 

 flowering before they perfect their seeds, the plants may sometimes 

 be rendered more durable. 



The first two sorts, as has been seen, are biennial, and the others 

 perennial; the former should of course be raised annually. 



They are all proper for affording ornament and variety, either in 

 the open ground or among other potted plants. The second and 

 third sorts are often considered as green -house plan Is, but they 

 succeed well in the open ground.
