''Consolida ajacis'' (syn. ''Consolida ambigua'', ''Delphinium ajacis'', ''Delphinium ambiguum'', doubtful knight's spur, rocket larkspur) is an annual flowering plant of the family Ranunculaceae native to Eurasia. It is widespread in other areas, including much of North America, where it was an introduced species. It is frequently grown in gardens as an ornamental for its spikes of blue, pink or white flowers. It may reach a meter in height. Since the aerial parts and seeds of ''C. ajacis'' have been found to contain diterpenoid alkaloids (see below), including the highly toxic methyllycaconitine, the plants should be considered as poisonous. ==Chemical Constituents== The first alkaloid to be isolated from ''C. ajacis'' seeds was ajaconine, reported by Keller and Volker in 1914.〔O. Keller and O. Volker (1914) ''Arch. Pharm.'' 251 207-216.〕 Since that time, over thirty other structurally related diterpenoid alkaloids have been reported; these are:〔V. Venkateswarlu, S. K.
