With proper care, most of the best spring flowers for arrangements last 7–14 days. Carnations, alstroemeria, and gerberas are the longest-lasting, often remaining fresh for up to two weeks. Tulips, lilies, and daffodils generally last around 7–10 days. Fresh water, trimmed stems, floral preservatives, and avoiding direct sunlight and heat are essential for maintaining longevity. Regularly removing wilted petals also helps. Following these steps ensures that spring bouquets stay vibrant, fragrant, and visually appealing throughout the season.
