cover in dry sand until the spring, when it may 

 be planted where it is to flower ; but as the seeds 

 Avhich are sown in the spring produce plants that 

 flower in the summer, this mode of preserving the 

 roots is not usually attended to. 



The seed should be sown in March on a mo- 

 derate hot-bed. When the plants are come up 

 they should have plenty of air admitted as often 

 as the weather is mild, and when they are about 

 two inches in height they may be transplanted 

 into a second very moderate hot -bed, or each 

 plant be put into a small pot filled with light rich 

 earth, and plunged into a hot-bed, from whence 

 they may be taken out into the borders with more 

 security than those that are planted in the bed. 



As soon as the plants have taken root in the 

 second hot-bed, they should be gradually enured 

 to the open air, which will prepare them for the 

 open garden about the beginning of June. The 

 seeds may be sown in a warm open border in 

 April, which will give plants for the autumn flow- 

 ering. 



From the size of these plants, which being 

 branchy and from three to five feet in height, they 

 are better calculated for the foreground of the 

 shrubbery than for the smaller borders of the par- 

 terre. They retain their beauty for a great length 

 of time, being frequently covered with blossoms
