A single foliar application of benzyladenine (BA) at 1250 to 3750 ppm stimulated axillary and rhizomic budbreak and offset formation in Hosta sieboldiana (Lodd.) Engl. Plants with no initial offsets formed a similar number of offsets as those with one initial offset but 143% more offsets than plants with two or three initial offsets. Growth index was either not affected or increased by BA application. Plant appearance was enhanced by late season offset formation in BA-treated plants.
