The seed should be sown in March, in any bed or border of 

 common earth, raking it in; and when the plants have got leaves of 

 two or three inches growth, they should be planted out in showery 

 weather, in rows eighteen inches distant, and at the same distance 

 in the lines: they soon strike root, and grow large, furnishing large 

 leaves, fit for use in autumn, winter, and the following spring. 



The perennial sorts are raised from seed in the same manner, 

 setting the young plants out in the summer in nursery-rows till 

 autumn, when they should be planted out into the borders, &c. 



The annual sorts may be sown in spring in the borders, in 

 patches, to remain. 



The roots in the perennial kinds may be parted in autumn, or 

 early in the spring, and planted out where they are to remain. 



Culture in the tender Shrubby Kinds. These are easily increased 

 by cuttings of the young shoots; they should be planted in pots in 

 the spring, and plunged in a hot-bed, where they soon emit roots at 

 bottom and shoots at top, and should be gradually hardened to the 

 full air: but cuttings planted in summer will often strike without 

 the aid of a hot-bed when planted either in pots or in a bed of 

 natural earth, under frames and lights, or covered close with hand- 

 glasses, and shaded from the mid-day sun, being occasionally 

 watered. 



The young plants should afterwards be potted off separately, and 

 managed as other shrubby exotics of the green-house. 



The last sort requires a warm dry green-house in winter, and to 

 be very sparingly watered. 



Some of the sorts are useful as culinary plants, others for the 

 purpose of ornament in the borders, &c. and the tender sorts in 

 green-house collections.
