CENTAUREA. [Compositae.] A large family of mostly 

 hardy perennials, comprising, however, some very ornamen- 

 tal annuals, which should have a place in every garden. 

 These may either be sown in the open border about the end 

 of April, and the plants thinned out subsequently to three 

 or four in a patch, to be left for blooming, or they may be 

 sown with other annuals in a seed-bed, or in pots, for 

 facility of transplantation ; in the latter case being sown 

 somewhat earlier, and coming earlier into flower. They 

 bloom from June, more or less onwards to September. The 

 very numerous hardy perennial kinds any of which are 

 worth growing as common border flowers grow well in 

 the common soil of gardens, and are increased by division.
