Although copper is supposedly bad for plants, I almost always put a penny at the bottom of my vases for cut flowers, I think the stalkers stay straighter longer, and they don't wilt so quickly.
i don't think it will help the lifespan of the flowers
Some of the top flowers that can last the longest without water are: Succulents: These plants store water in their leaves, allowing them to survive for extended periods without watering. Protea: Proteas have woody stems that help them retain water, making them resilient to drought conditions.

It is often included in commercial flower food packets to provide essential nutrients for the flowers.
