What advantage do seasonal flowers provide in arrangements?

Seasonal flowers offer the advantage of being often fresher and more sustainable because they are harvested at their peak bloom during the time of year they naturally thrive. This freshness is not only important for the overall aesthetic and longevity of the arrangement but also means that the flowers are more resilient, retaining their vitality and beauty for a longer period once incorporated into a design.

Additionally, choosing seasonal flowers supports local growers and reduces the carbon footprint associated with transportation, as these flowers do not require extensive shipping from distant locations. This sustainability aspect contributes to the environmental benefits of using seasonal blooms.

In contrast, while it might be true that seasonal flowers can sometimes be less expensive or more vibrant, these factors can vary depending on specific market conditions and flower types. The characteristic of being stored longer without wilting is generally more applicable to certain varieties of non-seasonal flowers which have been bred for longevity. Therefore, the primary advantage of seasonal flowers lies in their freshness and sustainability, making option C the most accurate choice.
