procni'ed from abroad, and sown on a warm dry situalion, in the 

 early autumn, in the places where the plants are to remain, as they 

 do not bear transplanting well. 'J'hc ground should be as little as 

 possible stirred about the plants. The former sliould have a dry 

 warm aspect where the land is poor, but the latter succeeds in such 

 as are more cool : these plants are sulHcicntly hardy to succeed in 

 the open air, when the winters arc not very severe. 



The last sort is raised by sowing the seeds procured from its na- 

 tive situation, on a gentle hot-bed in the autumn or s|)ring, and when 

 the plants are of sufficient growth removing them into separate pols, 

 to be placed under the protection of the greenhouse. It is much 

 more tender than the other sorts. 



The first and second kinds are highly ornamental plants in the 

 clumps, borders, and other conspicuous parts near the house, the 

 former flowering early, and w here many are together affording a fine 

 frasrance. • 



The other sorts, though more tender, are curious, and afford an 

 agreeable variety in assemblage with others of similar growth, either 

 ill the borders or among potted plants.
