The genus Crocosmia, from the Iridaceae family, includes the plants with obvious potential both for garden decoration and as a cut flowers. This paper evaluated the influence of the planting times and the size of the corms on the some characters of ornamental interest of Crocosmia plants, in the agroecological conditions from northeastern Romania (Iași). The corms of Crocosmia 'Lucifer' from two size categories (3-5.9 g and 6-9 g) were used, which were planted in the experimental field in November and April.The observations and determinations made during 2018-2021 highlighted the fact that from the corms with a mass between 6-8 g, planted in autumn, they ensured the obtaining of plants with the highest number of flower stems and the most flowers on the stem. Regarding the height of the flower stems, the best results were recorded in corms with a mass between 3-5.9 g, planted in autumn. In the case of corms planted in the spring, the results were less significant, except for the number of shoots in plants resulting from large corms (6-8 g). The flowering period was longer to the plants obtained from corms of 3-5.9 g, planted in autumn.
