Mimosa is a delicate flower and its duration is short, but it dries beautifully, retaining its natural charm. We appreciate your understanding and assure you that although its lifespan may be short, its beauty will endure in other ways. Mimosa cut in water usually lasts between 3 and 5 days, depending on the environmental conditions and the care given to it. To prolong its life, it is advisable to keep it in a cool place and change the water regularly.
