Abstract: The Narcissus poeticus (L.) species stands out from other narcissus due to its unique ornamental and sensory values. In our experiment, the flowers of N. poeticus were harvested at five different stages. After cutting, the plants were placed directly at room temperature or at 4 °C for 1 week. The opening status of the flowers was recorded every 12 h, and based on this, the ornamental value of the flowers was calculated. Additionally, the flower diameter, the scape and flower weight, the dry matter content, the water soluble K, Ca, and Mg content of the plant parts, and the chlorophyll content of the scapes were measured. The complete senescence of the stored flowers was noted to be earlier (after 6.6–7.5 days) than that of the fresh flowers (7.5–8.5 days) and depended on the bud stage at harvest. Flowers opened from all the buds, but the flower size was smaller in the early developmental harvest stage (a 10 mm reduction in diameter and a 0.38 g reduction in fresh weight between the green bud and the large white bud harvest stages). Cold storage delayed further bud development and reduced the flower size in several cases, but it increased the maximum decorative value of the flowers for those flowers that had been harvested as big white buds.
