In order to study the most suitable planting date, planting site and variety of hoary stock for the supplying at spring season, an experiment was conducted as split-split-plot arranged based on randomized complete block design with three replications at experiment station of Shahid Bahonar University of Kerman in 2016-2017. Treatments were planting dates (5 September, 5 October, 5 November, 5 December, 5 January) assigned to main plot, planting sites (inside and outside of greenhouse) as subplot and variety (two red and white ecotypes and two violet and pink breeding varieties) as sub-subplot. The significant difference of planting date was detected in plant height, number of days to budding and flowering, floret and inflorescence diameter, number of florets per plant, fresh weight of floret and plant, and vase life of flowers but did not detect in inflorescence height. The planting site had significant effect on all the traits except plant height, inflorescence height, and leaf number per plant. The results showed that the delay in planting decreased number of days to budding and flowering in all the varieties and both planting sites. The growth period of local varieties was longer than the breeding varieties, significantly. Planting outside the greenhouse had more appropriate conditions than inside. In general, planting the local red variety at 5 October and out of greenhouse conditions was the most suitable treatment for supplying the hoary stock to the market on the first of spring.
