The study was carried out to evaluate the variability of some morphological characteristics in six cultivars of gladiolus, 'Blue Frost’, 'Green Star’, 'Nova Lux’, 'Peter Pears’, 'Priscilla’ and 'Purple Flora’, cultivated in the climatic conditions of Craiova city, Romania. The results showed that the minimum number of days from planting to flowering and the maximum plant height, number of leaves per plant and spike length were recorded in 'Green Star’ cultivar, which was superior to the other cultivars. 'Nova Lux’ performed the best for the number of florets per spike (16.5), and 'Blue Frost’ for the diameter of floret (12.26 cm), wich are important quality indicators. Among the cultivars 'Purple ʻFlora’ and 'Priscilla’ had the longest flowering duration. The coefficient of variation in terms of vegetative and flowering parameters, ranged between 7.75% for the number of leaves per plant and 19.89% for the number of florets in inflorescence. The highest coefficient of variation was obtained for the flowering duration (23.73%).
