Tlie first throe sorts afiord at) agrerafcte variety 

 in the borders and chimps, as tli< y continue long 

 in flower. The Four following kinds asre likewise 

 hardy, and afford variety among other potted 

 plants in the tfpen air during the summer. 



The other species are more tender, but pro- 

 duer an agreeable effect among $hfe su.-.- and 

 iieen -house collection*, from the great beauty and 

 ontinnanee of the flowers in many of the sorts;

 Subulate, upright, commonly quite entire-, the 

 stamina in the hermaphrodites have five (ila- 

 hierrtSj capillary, verv short : anthers cylindric,

Oidfure. — These plants maybe increased bv 

 sowing thescedsin patches, in the perennial sons 

 :n the tiiiuimi, and the annual ones in thesprkig, 

 in the borders, clumps, or other parts where the 

 plants are to remain. Thev should afterwards 

 be kept free trom weeds, and be properly 

 thinned. 



The i>_-rriii)ial kind may likewise be increase! 

 by off-sets or slips from the roots, which should 

 be planted out in the autumn, where the plants 

 are to continue. 



The first kind requires a dry soil and sunny 

 exposure. The perennial sort flowers the se- 

 cond year. 



They are. plants which afford ornament and 

 varietv among others of the flowering kind.
