 July or August. The following are very handsome annuals : 

 field larkspur (D. consolidea), common in fields, a loose and

 white, or pink, showy. Rocket larkspur (J). Ajacis), a com-

 larkspur (A nudicaule), a dwarf plant with peltate leaves 

 and upright, almost leafless racemes of beautiful scarlet-red 

 flowers, and the dwarf larkspur (D. tricorne), a plant seldom 

 a foot high, with five-parted leaves and showy blue flow-

 roots are poisonous and must never be left in the hand of a
