Considering the importance of improvement in cut flowers production, some experiments was carried out to determine the effects of planting depth on growth, flowering and cormels production of white and pink gladiolus cultivars. The trial was conducted in a randomized complete design with five replications by comparing five planting depth including of 4, 8, 12, 16 and 20 cm. Medium size corms were planted with planting distances of 10 cm in rows and 25 cm between rows in Quonset greenhouse in the middle of February. Increasing planting depth delayed sprouting and caused a significant decrease in emerging percent. The depth of planting also affected flowering time but had no effect on stem and inflorescence length and florets numbers. A significant decrease in number of collected cormels at the end of growing season was revealed as the planting depth increased. Considering all assessed factors the best results was obtained at the planting depths of 8 and 12 cm.
