 in the gardens, which flower early. The one called Crown 

 or Carnation Daisy is twice the size of the common varie- 

 ties, and has white and red petals alternately and very 

 double. Loamy soil, inclined to moisture, is best adapted 

 to their growth. 



Campdmda. This genus affords very many ornamental 

 plants for the Flower garden and Shrubbery, and they flower 

 superbly during the summer, agreeing better with our cli- 

 mate than with that of Europe. Many have two successions 

 of flowers, C. persicifblia alba plena ; C. perdcifdlia coerulea 

 pUno ; C urticifoliaj white. Of this last, there is also a 

 double variety. C. specibsa ; C. glomerata ; C. versicolor , 

 with several others, are worthy of a situation in every garden. 

 Their roots are strong, fleshy and fibrous. They are easy of 

 culture, and will retain their situation in the severest of our 

 winters. C. grandiflbra is now Walilenjjergia grandiflbra. 

 It has superb large blue flowers, stems are slender, and should 

 be supported as soon as they grow.

 blooming from April to June ] it requires a light rich soil ; 

 is a half-shrubby evergreen plant.

 and possesses many fine species. It is a matter of astonish-

 our collections. C. gldhra ; C. ohliqua ; C. harhdta; C, 

 airopurpurea ; C pulcMlla ; and C. specibsa ; are all 

 handsome, and flower from May to September ; corolla large, 

 ringent, ventricose ; flowers in spikes or panicles.

 C. sincnse, of which there are about ninety, all desirable ; 

 but in small gardens, where there is a deficiency in room, 

 the following are select in color and quality : Admiration j
