It may be necessary to state further, that there are 

 a great variety of beautiful double- flowering perennial 

 herbaceous plants, that will not produce seed ; many 

 of these may be obtained of the Florists, and should 

 be introduced into the regular flowerbeds; the mode 

 of increasing such, is by layers, cuttings, offsets, &c. 

 detached from trn old plants. As the earth within the 

 flower beds will need to be fresh dug and replenished 

 with good compost or manure, once in two or three 

 years, it may be necessary to take up all the perennial 

 plants at such times. Such roots as may be overgrown , 

 should be deprived of their surplus offsets, and may be 

 planted in a nursery bed, or returned with the parent 

 plants into the regular flower beds. 



In removing plants into the beds where they are 

 intended to flower, great pains should be taken to 

 preserve some of the earth to the roots, and the ground 

 should be previously brought into good condition, so 

 that they may strike freely, and produce their flowers 

 in perfection. The plants should be so arranged that 

 they may all be seen. The most dwarfish may be 

 placed in front, and others in a regular gradation to 

 the tallest behind ; or the tallest may be planted along
