Succulents are ornamental plants that are popularly used in landscaping and as potted plants. Miniatureplants that are planted in miniature pots for small spaces or tables, or in elaborateaccessories such as key chains, key holders or hanging pots, have recently become more popular. Their unique characteristics and aesthetic appeal have increased their demand especially for those species that do not grow extensively during transport or for special cases in which they are placed into tiny containers to be used in key chains. This study investigated the effects of the plant growth inhibitors chlormequat, paclobutrazol, and daminozide, on two Echeveria species, Echeveria ‘A Grimme One’ and Echeveria ‘Little Rose’. Results revealed that the plant growth inhibitors successfully controlled the growth of Echeveria species at specific concentrations. Among the inhibitors applied to the succulents, paclobutrazol at 100 ppm was found to be the most effective treatment for both the species.
