The effect of auxins: IAA, IBA and NAA in concentrations of 1.0, 2.5 and 5.0 mg/cubic dm on rooting of Hebe buchananii (Hook) and Hebe canterburiensis (J.B.Armstr.) Prostrata in vitro was examined. Shoots used in the experiment were excised ffrom aseptically grown shoots on 1/2 MS media. Auxins in the experiment were showed to have a positive effect on rooting of shoots of Hebe buchananii (Hook) and Hebe canterburiensis (J.B.Armstr.) Prostrata in vitro. The biggest number of rooted microshoots and the longest roots of Hebe buchananii formed in presence of IBA. On the media supplemented with IAA in concentrations of 2.5 and 5.0 mg/cubic dm, IBA in concentration of 5 mg/cubic dm and NAA in concentration of 1 mg/cubic dm 100 percent of rooted shoots of Hebe canterburiensis Prostrata were obtained. The biggest number of roots occurred on media with 2.5 and 5.0 mg IAA/cubic dm. NAA added to the media caused callusing of the shoots base
