GARDEN FLOWERS. 125 



CREPIS. See TOLPIS. 



CRISTARIA. [Malvaceae.] Hardy herbaceous perennial, 

 thriving in peat, and increased by division. 



C. coccinea (scarlet) ; hardy perennial ; 6 inches ; flowers scar- 

 let, in August ; Missouri ; 1811. 



CROCUS. Beautiful dwarf hardy bulbs, with grassy leaves 

 and showy flowers, of easiest culture in common garden 

 soil. The bulbs should be planted in October or Novem- 

 ber, about two inches deep, in clumps, or rows. They 

 should not be planted singly, as they are far more effective 

 if put in groups of six, twelve, or even more, the groups 

 being proportionately distant. There is another race of Cro- 

 cuses, the autumn-bloomers, comprising some very. splendid 

 species, which bloom in the end of October and through 

 November, and are equally useful, as ornaments, with the 

 spring Crocuses, in consequence of blooming when other 

 flowers are out of bloom. Many of these, however, are very 

 scarce. They should be planted in June and July, and in 

 other respects require precisely the same treatment as the 

 others.
