Abstract
This experiment was conducted to investigate growth and flowering characteristics of Celosia argentea native to Korea treated by monthly sowing from January 20 to August 20 in the field. As sowing date delayed from January to June, the days to flowering were increased. Seedlings sown on February and March planted in the field on April and May were shorter, 31 days to flower, shorter plant height, much more number of flower than those of sown on May and June planted in the field on July and August which means Celosia argentea may be facultative short day plant. And the seedlings sown on February and March were precious ornamentals for bed plant from summer to fall, however, the seedlings sown on April and May were valued for bed or cut plant producing in fall.
