SELECTION OF PLANTS. 187 



July ; it grows vigorously in a peat border, and will thrive 

 in the most exposed situations and driest seasons. A divi- 

 sion of the crown of the roots is the usual mode of propa- 

 gating it, unless it ripens seeds, which sometimes happens. 

 It is a native of North America ; and the plant may be 

 seen in the garden of the Horticultural Society. 



584. ASTER CONCINNUS. Neat Aster. 



Class 19th. Syngenesia Superflua. 



A hardy Perennial, growing nearly three feet high, and 

 flowering in September and October. 



A native of the plains and woodland of North Ame- 

 rica. 



It is remarked by those who have gardens this is one 

 of the species the most worth cultivating, because of the 

 gay colour of its flowers and its neat appearance. The 

 stem is generally tinged more or less with purple. It is. 

 propagated by a division of the root. 



585. COLLOMIA COCCINEA. Brick-red Collomia. 



Class 5th. Pentandria Monogynia. 



A hardy Annual, a native of Chile. If sown rather 

 thick in a mass it will shew itself to advantage. The 

 seeds should be sown in March, in the open border, when 

 the flowers will appear in June ; if again sown in April a 

 second crop of flowers may be had in September and 

 October, seasons which suit it rather better than in the 

 dog-days. 



It may be seen at the proper season in the garden of the 

 Horticultural Society.
