A rapid clonal propagation system for Clerodendrum colebrookianum Walp. (Verbenaceae), a anti-hypertension folk medicinal shrub has been developed. A range of cytokinins has been investigated for multiple shoot induction with shoot apex, axillary shoot, leaf, petiole and root explants. Optimum shoot induction occurred with axillary buds using 6-benzyladenine where an average of 21 shoots were produced per explant in 6 weeks. Subculturing the newly produced shoots, by separating into groups of five shoots, produced an average of 43 new shoots per culture within 4 weeks. In vitro rooting and weaning of over 200 plantlets was completely successful. Cytological studies revealed no visible abnormalities in chromosome number.
