The study effectuated during the period between 2014 and 2020 at seventeen Hemerocallis cultivars ('Arctic Snow’, 'Aten’, 'Black Prince’, 'Bumble Bee’, 'Campfire Embers’, 'Cartwheels’, 'Chicago Cardinal’, 'Chicago Picotee Memories’, 'Cologne Rocket’, 'Custard Candy’, 'El Desperado’, 'Frans Halls’, 'Mikado’, 'Pandora´s Box’, 'Spits Beauty’, 'Stella de Oro’, 'Strawberry Candy’) held in the collection of the University of Agricultural Sciences and Veterinary Medicine of Iasi had as purpose the analysis of some ornamental interest features, including of the flowers and of the phenology of the flowering. The results showed that from a morphometric point of view, the studied hybrids differ between them regarding the total size of the flowers and of the floral components. Also, the dimension, the colour and the form of the tepals differ in the cultivars, and also at the same cultivar (between the outer and the inner tepals). The flowering time at the Hemerocallis hybrids cultivated at Iasi was of approximately one month, except for the 'Arctic Snow’ cultivar (approximately 3 weeks) and 'Stella de Oro’ (7-8 weeks, through repeated prolonged flowering). The period in which most of the cultivars are blooming coincides with the month of July (with extensions in the last decade of June and the first decade of August).
