Young plants of Lantana camara L. subsp. camara grown into pots in a glasshouse, were treated with the growth regulators paclobutrazol and triapenthenol, in order to control their heights and to produce flowering compact plants. The treatment with 100 mgL-1 paclobutrazol (foliar sprays applied to runoff), provides plants with better commercial quality for use as indoor flowering pot plants because, while it causes reduction in height by approximately one-third it also increases by nearly four times the number of flowers compared with control plants. All the treatments, except the control, showed dark green foliage color. It was also concluded, that one or more micrometeorological factors affected significantly plant height. All the treatments were made twelve days after the pinching of the plants in the second internode from the tips, when the length of the new-developing stems was 1 cm approximately.
