82 GREEN-HOUSEREPOTTING. [MARCH. 



ceous ; colour red and yellow ; though small, they are 

 very neat. C. nana and C. ilicifblia are amongst the 

 best ; if grown from seed, they will flower freely the 

 second year ; drain the pots well. 



Cinerarias, Cape aster, about twelve belong to the 

 Green-house. They are herbaceous, or half shrubby, 

 soft wooded plants. C. specibsa, C. amelloides, (now 

 called dgathcea ccelestus^) C. purpurea, and C. landta, are 

 among the finest; flowers blue or yellow; the latter is 

 considered the handsomest of the genus. The exte- 

 rior petals are bright purple', and the interior ones 

 white, and with Jl. ccelestus, flowers most of the year ; 

 flowers syngenesious and star-like. The herbaceous 

 species must be treated as previously mentioned for 

 that kind of plants.

 cies, principally natives of Europe, consequently hardy 

 there, and form a great ornament to their gardens, 

 being very abundant and various in flower ; but with

 no doubt, however, but, through time, some kinds may 

 be grown that will withstand the greatest cold of the 

 middle states ; they are low shrubby plants of easy cul- 

 tivation. C. ladaniferus, C. monspcliensis, C. sdlignus, C. 

 popolifblius, arid C. undulatus, are perhaps the best; 

 the flowers are of short duration, frequently only for one 

 day ; but the quantity makes up this deficiency, being 

 constantly in flower in May and June, and sometimes 

 flower again in autumn. C. creticus is most productive 

 of the Gum laudanum, which is secreted about its 

 leaves and branches. The flowers are generally five-
