This study was carried out to investigate effect of $GA_{3}$ foliar application on the growth and flowering of Limonium spp. 'Ocean Blue' to develop an effective $GA_{3}$ treatment method for a year round commercial production. Plants were treated with different concentrations of $GA_{3}$ 0, 100, 200, 400, and 800 mg.$L^{-1}$ in summer, and 0, 100,200, and 400 mg.$L^{-1}$ in winter at seven weeks after transplanting. The effects of $GA_{3}$ treatment time (0, 10, 20, 30, 40, and 50 days after planting) and plant age (raising during 3, 5, 7, and 9 weeks) was investigated. The $GA_{3}$ treatment advanced bolting and flowering with little difference between the two seasons. In a summer culture the effective concentration of $GA_{3}$ ranged from 200 to 400 mg. $L^{-1}$, while in winter it was found to be 400 mg. $L^{-1}$. The $GA_{3}$ treatment at 10 days after planting significantly reduced days to flowering. However, the greatest cut flower yield was observed in plants treated at 20 days after planting. The $GA_{3}$ treatment to different age plants did not show a significant effect, except in the oldest (nine weeks old plants). In conclusion, to induce early flowering in Limonium spp. 'Ocean Blue', the proper concentration and time of application of $GA_{3}$ was 400 mg.$L^{-1}$ $GA_{3}$ treated to nine weeks old plants at 20 days after transplanting.
