I live in North Carolina, if that matters. Looking for an arrangement that has height and is aromatic, if possible.
Which cut flowers make the best, long-lasting fresh flower arrangements?

FlowersBirthday FlowersSympathy FlowersCarnations and mums last the longest of the easy to obtain cut flowers. Sprays of orchids are long lasting too. Blue iris and lilies are the shortest lived. You can extend the life of flowers in a vase by keeping them as cool as possible and recutting the stems and changing the water every day.
Reply:I really like freesias. The stems are very elegant and usually look great in a tall vase. They are a relatively long lasting cut flower...about ten days ( to two weeks if kept cooler). Buy them in bud for best results. They are beautifully fragrant, but subtle enough that most men don%26#039;t complain!c++
